Thank you for your reply.
I finished high school two years ago, but I still have one final exam to pass. I was working for a year after graduating, it was very stressful. Now I don't have a job, can't go to uni until I pass algebra (I take it on Thursday for the third time). People I used to hang out with, well, they moved away and I stopped going outside and I'm pretty isolated. I went back to the depression, OCD and constant worrying about being schizophrenic. I only talk to my parents now.

I also remember one another thing from my childhood- I was not only really quiet/didn't cry most of the time, but never really talked to anyone even if I was suffering. When I was in primary school and broke my hand on my way there, I didn't told anyone until it got really bad. I've spent the whole day at school like nothing has happened. The same thing goes with other things.
