Sounds like an anxiety disorder. I also had a difficult time with it and it became a pretty brutal depression. You should look at your own life style: How much time to you spend outside with friends, are you a social person? Try to communicate more with people. People with disorders like this usually are thinking too much. I know this sounds a little vague, but if you do most of the day nothing at home it can become something like this.
Are you in good shape? Do you have obesity or are you underweighted? Do something about it.

Also, don't be ashamed to talk about it with someone you trust. You can go to a psychologist if you feel it is getting out of hand.

I do breathing exercises, regular exercise and I take B vitamins for the nerves. Your case sounds more serious than mine though. If anything you may have to seek out professional help.

I'd avoid the Mary Jane too. Trust me look at my name. I see it as an 'amplifier'. In the past when I was in a good mood and consumed the stuff with friends, it boosted that mode. One time I did it when I was stressed and anxious. Jeeeeez ..... talk about paranoia! My heart was racing, I was sweating profusely and the worst thoughts pervaded my mind. Then and there I decided to stop.

Im taking Lovan and Ativan for my anxiety. It helps doing something that keeps you in the present. Personally i do lots of excercise and i run a website to keep my mind busy from my problems. Have you tried Cognitive behavior therapy - im doing a couple of modules now. It has worked a bit, the problem it takes a long time and you have to face the problem head on. My anxiety went through the roof in november i had the same problem as you, so you are not alone.

Depends, a 100% indica will relax the shit out of him... there's always the risk of it going the other way and making the anxiety 10x worse, but that risk minimal with the right strain and experience

I know where you're coming from, I've been there. Prayer/meditation would help, but you need some detoxication from something.

Find a social group you are interested and go on a retreat or a camp in the outdoors, leave your house, your possessions and just free yourself from everything that's binding you down.

That's my best advice for you.

As someone who knows what you're going through, go outside.

I mean it. Get away from the computer (ESPECIALLY if you're the kind of person who googles to see what is wrong with them), away from games, away from sitting and/or laying around. Go outside and do something. Doesn't matter if it's raking up the leaves leftover from fall or just cleaning up around the yard. Do anything to get you active and working your muscles. It will get your mind off of everything else. The less you are doing the more likely you will get stuck in negative thought.

If you really do need meds, well, Zoloft is on the lower end, plus they all effect everyone differently. Maybe ask your doc to change what you are on. Maybe suggest Lexapro. Stay away from Xanax, it's no good for you. Lexapro kind of just mellows you out and while you will still have thoughts, it shouldn't be anywhere near as bad. It is the only thing to help me out and I am already in the process of weening myself off it and getting back to using nothing. It's my first med and I have been on it for ~2+ months. I just hate having to take meds.

Exercise and try to keep very active is my best advice. Spend time in the sun.

Not sure what kind of anxiety you have, but I have health anxiety. Every little thing gets my mind racing.

A1 advice. The more you do with your body, the less you do with your mind. Try to focus on your body and strength, it will distract you and also give you better chemical balances in general.

Any kind of drug is probably a bad thing.

I would suggest a good walk/hike. Where you're at, I would suggest something fairly vigorous, like a large park or hiking to a waterfall. Focus on the adventure. Focus on the goal. Allow your mind to escape thinking of its basic functions.

Also, talk it out. Like you are doing here. Express what you are feeling.

You should definitely see a doctor about this. I don't know too much about this, but it sounds like you have high blood pressure, stress, anxiety and depression. Something is probably bothering you alot.

Oh man, I remember these from when I was a child. Sounds like a bit of an anxiety fit as many have mentioned.
Yours seems quite severe! I thought mine were brought upon by allergies, then I'd just have this intense heat and felt like people were staring at me all the time until I forced myself to relax. Massaging your wrist will slow your heart rate, which may allow you to calm down. Just reassure yourself.

Guess I just grew out of it. Not really sure tbh.
