I have simular problems as well with quite a bit of OCD (still have to get diagnosed with that), anxiety and depression (probably because of it all).

It's just a really terrifying way of thinking. If you don't think that Its major, try and push yourself harder. For me I've tried everything. Today I was worrying about hundreds of things, skipped school about ten times today which eventually lead me back in the door and so on. I had to go home twice. (in a period of ten minutes, I phoned my mom five times, walking in and out of the door because I thought my therapy was today). I eventually ended up staying for the rest of the day and it walk he'll. To add to that, I pulled a muscle on my neck while reaching for the alarm clock. That's just a day for me.. I think erratically and irrationally. I feel trapped. I always act like the guy I am and try to tough it out but I'm getting to a really low point. I just call it the "all or nothing" way of thinking. There is just black or white. No In between and I'm still trying to find a solution for it..
