If he's got a mental condition, whatever that is, that might explain why he can't get a job. Any condition, illness or disability makes everything a lot worse.

Similar story to mine and similar average score of 63% for course and 1 failed unit and I also live in Australia. I could not gain any relevant work experience due to hot competition but I did not apply for graduate positions because I knew my grades were not good enough. I gave up looking for work in accounting within 3 months and tried to do a Drafting course that I quit within 2 months. Seeing it was going to be 3 or 4 more years of study and minimal chance of securing job I quit the Drafting Course. I was also too old to take on a trade apprenticeship, because over 21 years of age adult wages must be paid instead of the lower junior rates. I have never held a drivers license either, I failed it a couple of times and I just gave up because driving for me was too difficult and triggered my anxiety. 

The OP sounds like an American. If so, there is simply no truth to the idea that one cannot find work. It may require relocating, taking a job thats not exactly what he wants, or other sacrifice. But, in much of the US, you can drive five minutes without running into ten companies looking to hire. They may not be dream jobs. But, how many people have had to take jobs they didn't like at some point? I'm guessing its close to 100%.

And, yes, relocating is not ideal. But, tough shit. Sometimes, you have to do things that are not ideal.

When it comes to depression and the problems that brings.... well, that one is tougher. It often takes professional help to overcome, and the paradox of depression means that one has trouble getting themselves to avail themselves of that professional help. It can lead to a downward spiral. Still though, ultimately, the sufferer *must* muster the strength to get the needed help. It simply cannot be done by others.

In other cases, the depression can be solved simply by standing up, looking in the mirror, and handling your business. In this case, get yourself out of the house, get a fucking job doing anything, get some exercise, and start the ball rolling in the right direction. It spirals that way too, for many people.

As a person that hires people for my own business, I can tell you the problem here - "I have applied....online".  I know that's standard practice in many businesses.  But, it is *always* possible to show up at the office, the store, the warehouse, or wherever and show that you really want the job.  If you show up, or even just work the phone until you reach the person that does the hiring, you're like one hundred times more likely to get an interview.

Applying online for thousands of jobs shows me that you're half-assing it.  You can't possibly put in the work needed to actually get hired for more than a handful of jobs each week.  And, if you do that for a few weeks, you'll have a job.  

Indeed but it does not always have to become impossible,im doubtfull he would be happy if he did have a job because of the required social interactions in the workplace.

He has welfare,that makes him able to not need to worry about those things and at the same time it can keep people stuck in place because it is not needed to progress for surviving.And still what he said about the mails does not look sincere at all as in it seems highly doubtfull that is realistic,something about it will be true but not that exaggeration of 1000 send and no response.

I will say most responses here are very much not helpful and its because most of you are looking to judge instead.  Leave the judgement and assumptions out and actually look for more positive ways that can help this person out.  None of us live this person life or even fully understand what this person is going through and the depth of their predicament.   

So with that said my advice is for this person to check and see what are the social programs available on welfare they have available.  See if there are some social services that can help with resume writing, Job placements and therapy to help with specific things needed to not only land a job but also keep it.  A lot of time when someone is on welfare, they do not take advantage of all the support and help that is available.  The easiest way to get out of your situation is take steps that are different then what has kept you in the same place for so long.

We can only speculate his personal situation and it is up to him to see if there is any valueable information in this thread he could use but with his current seemingly mindset i do not think he can get something usefull from the outside of his mind when his inner self is the thing blocking everything that could possible positivitely effect him.

The things that trouble him as an autist i can personally relate a lot to so i just try to give feedback on that,what made me survive is being forced by others in situations i did not want to be in as a kid,so i did learn how to interact with people in real life but i never recommend this method because i was not a happy child to say it lightly.

Bolded: I agree and even that will not be easy but just small steps are enough as long as that person keeps improving,not much more important as building on ourselves and making the people we care about happy.

Gonna be honest here, you would have better luck sending a text message full of genuinely terrible typo's and text speak to someone in HR than mailing out a cookie cutter copy paste CV, the text message might at least get you some reply as being different and directly seeking out someone in charge of hiring.

You need to actually apply for jobs that you're interested in and approach them as though you are interested, if they get a CV which probably includes the fact that you're sending it out because some jobseeking company told you you had to or your benefits would be cut then that CV is going right in the bin, look at a company you want to work for and start to see who to approach there and what you'll do to get in the door, if you aren't suited and booted correctly for meeting someone from HR go and sort that out right away, always dress for the job you want, and if money is an issue go and talk to anyone involved with your benefits they should be able to point you in the direction of getting some funding for that or they'll point you in the direction of some charity shops which you can often find very nice interview suits and such inside for very little cash.

The OP to this thread genuinely sounds like you've committed to failing before you even start, that is the absolutely wrong attitude to have when it comes to seeking out work. Approach with a little more confidence than writing stuff like "I'll literally work some hours for free if you let me in the door" because that doesn't look like someone who wants to sustain themselves, that looks like someone who wants to retain a benefits payment and is just looking to tick a box of "I'm working somewhere now, leave me alone" to keep getting that payment. See what you can do about finding out the HR people behind the companies you're gunning towards and try and direct your approach to them, don't just wander in and drop a CV at reception or email the "contact us" email address that you'll find online with an empty email with just the copy paste CV attached to it.

There is nothing wrong with speculating internally but try to leave it out in response.  The reason I say this is that when someone is in a bad place, the first thing you ignore is when it feel like people are judging you.  Most people cannot get beyond the judging part to hear the solution part.  A lot of times its not the content people say that is wrong its how it's said. 

I want to encourage this person to look for means out of their situation not prop myself up by saying "I never had that problem", "Well you half assed this" or the more helpful "Well if you did this you wouldn't be in this situation etc."  None of those types of comments actually help because the listener never gets to the solution after already getting triggered on how it was delivered.

To your last statement, I totally agree.  This is the true point that in order to change status, you must step outside your comfort zone.  I encourage this person to make the small steps that is needed to step outside of the comfort zone that has kept them where they are at and do a few things different and look for a different outcome.

Getting a job when you are young is way easier than being middle aged unable to find work.
I am simply unemployable and I do not have any work experience and no resume.
Staying on at school instead of doing retail/fast food job was my biggest mistake.
At 15 or 16 I would been able to work full time doing retail or fast food job and I would be doing that job for life.

Education for me was a complete waste of time and it did not lead to better employment opportunities and I ended up unemployable.
I live in a country that does not value education, people with less education in my country tend to do better than wasting time with further education.
Having a trade is regarded as better than doing a university degree and provides better employment prospects.

I do not live in the UK or USA.
I live in a country that does not value education.
It is a lucky country because without an education you do better than the people who waste the best years of your life on pointless qualifications.
