This!

There is a reason there are psychiatrists, it's their job to help with these kinds of problems. And they can help if you let them (been there donne that).

Professional or bust, people here won't be able to help you. Hell the internet thrives on othere people's pain/problems.

It just came out of no where, i honestly couldn't put my finger on it

I was kind of thrusted into a scenario i wasnt equipped for. I was struggling in the job department while my wife was achieving national recognition for her achievements, i felt id worked so hard to get my qualifications and wasnt getting the job or recognition i thought i would

My advice is to not seek it cause it doesn't exist. Do things that you like as long as it doesn't harm someone else, and settle with that, a stable life with no ups or downs, even if it can get boring it's a lot better than all the drama that people obsess over.

I used to consider myself very confident before my ego took a big hit.

Iv recently landed mt dream job which i thought would have helped but still feel empty.

Im not really sure what triggered my depression 

Not great, i still feel empty so i feel only half there 

The one time I got depressed was because of a career move away from my home and social circle. I used people (a lot) to fill that emptiness in my heart from starting my social life all over again... cutting corners socially is probably the best way to describe it. My depression was short lived... about 5 months. Eventually I snapped out of it when I started visiting family and true friends during vacation time.

The best advice I can give from personal experience is get in touch with family and friends.

Are you depressed because your wife left you? I can't give any advise on that unfortunately. I have a bad habit of not dwelling on people or girls when I'm through with them as cold as that sounds. Maybe that's advice within itself.

Problems 

Low self esteem

Lack of empathy 

Lack of direction, dont really know what i want in life 

Feel as tho iv underachieved

Suicidal thoughts

No motivation 

No goals anymore, all have been crushed or forgotten 

Im a programmer working for a huge company in Sydney 

You're in a new country, dream job and new girl. Try and seek some professional help definitely, once that starts helping and you get onto something that hopefully improves your mental health. You can actually see how lucky you truly are, good luck my friend.

Don't seek help or advice from forums is my first advice. My next advice, seek professional help. You have a mental illness and when you have a serious illness you go to the doctor. AND you get the support of family and loved ones to help you through it. But get diagnosed and start treatment first, that way when you talk to your family you actually have a professional opinion to present to them, which helps them with acceptance that you do have a serious condition and not just making shit up.
