I have no hobbies / interests?

Hello! I am 17 years old, and I have depression and OCD. My OCD is mainly concentrated around school and college. I've had full blown panic attacks (most recently last night) over having a C or B. If it isn't obvious, it's taken it's toll. I have constant headaches, I always have an upset stomach, I'm withdrawn and all I think about is school work and succeeding. It came to realization the other day that I have no hobbies or interests to take my mind off the stress of succeeding in school. Nothing interests me anymore, and I don't know what to do. I've tried numerous things (drawing, hiking, biking, reading, etc) as hobbies and just none of them interest me. Do you have any advice? I can't keep living with the 24/7 stress of school and need a healthy outlet to release my stress. Thank you!

Dear Katie, In my opinion you should be around people,don't worry if you aren't professional in something,every begining is very difficult.Have you ever tried teamgames? For example ,handball,basketball,football,voleyball,table tennis or just chess? When i am angry i go running with one of my friends.How often do you eat a day and what? If you eat too much in the evening you can't sleep well. Have you ever tried searching on the internet for interesting hobbies? Are your parents strict? How many hours do you study for the C? Don't worry about your C's,you should focus on those subjects that you are interested in. You will be working in these areas.
