I really do not understand what is wrong with me. I cry because I failed my driving test multiple times and cant seem to pass it. I cried because I just passed the essay I worked hard on but others got a first. I cried because I was in hospital and my health is weak. I cried because I have low social capabilities and cannot seem to get along with anyone very well.

This is not the life I wanted to live, neither do I understand why God is putting me so much pain. I just want a few good friends, good family and want to be happy and healthy. I do not want to go through these feelings because I really believe that I deserve happiness and have been like this for way too long.

Don't know what to do from now on basically.

Your first step would be to go to your family doctor to talk to them about what you said here. Get a referral to a therapist or psych doc to talk to them. I don't know if you will get perscribed medication or not and will not attempt to diagnosis you as you need a professional to do that.
May I also recommend you keep a journal. Draw in it, write in it just put down how you are feeling in it and you may see a pattern.
Good luck as I have the same issues at times

You have asked us this before - have you reread your old posts.

"From anxiety to psychotherapy, CBT, medication, journaling I've tried everything. I also tried reaching out to people more, and made new friends when I moved away to university, however I don't see them often because of the long holidays I have." --- that's from last April

I forget if I said this before, so I'll say it again: I think you need a very thorough MEDICAL exam, one that you might not be able to get where you are. Less than a year ago, you were in hospital and very weak, and never even said WHY!!! The mind and body are all one.
