Not being a medical professional I would call the anxiety, hate crowds, can't make choices, can't hold a job problems more of an anxiety/depression condition. I would bet that most of us in present day society experience that to different degrees during our lifetimes.
I tend to be Type A personality with a degree of obsessive-compulsiveness which has been both positive and negative in my life. I have been a very good high tech person for almost 40 yrs. I know it is more because I refuse to give up when trying to resolve a problem than because I am just smarter than others. Maybe that "win or die" gene is why humans have survived all these thousands of years. I have also suffered from extreme anxiety and on some occasions knew that I was probably "clinically" depressed.
What I discovered almost 20 yrs. ago was that I could make my obsession something that helped relieve the anxiety-depression part! I can only get into this when the facilities are within a reasonable distance and it takes weeks of doing it every day before I start literally craving it every evening and all weekend. I LOVE BASKETBALL. I'm not really that good at it but it doesn't matter. I love to start out on a court all by myself and just at my own pace shoot, jump, run and everything else. I fantasize that I'm taking the game winning shot in front of all of the people that I know. If I miss (most of the time) then just mentally hit "reset" and now the next shot is the "real" one. Eventually you realize that you can play longer and are even developing some skills. People at the courts see you around and start asking if you want to join a game. Don't get to competitive and DON'T GET HURT. Winning doesn't matter. The real addiction is that feeling of complete exhaustion when you finally go home and fall out in the floor. It's wonderful. You sleep like a baby. The anxiety greatly improves. People notice the spring in your step and pay you complements.
There's probably any number of physical activities that others could get into the way I can with basketball. It's really hard to explain the "addiction" to it but I couldn't do this with something that I viewed as "hard work" like weight lifting, or just plain jogging. However, after months of basketball you start feeling so strong that you might want to add some weight lifting because it will make you a better basketball player!
I know this is long but it takes some explaining. Anxiety and depression will get better with better health from exercise, eating right, sleeping right, etc. But, how does a depressed person start exercising? Hey, I can feel like life is not worth living but if someone tosses me a round ball then that old feeling comes back and "it's on."
