Is it possible to develop a disorder like OCD in your teens?

I would say take it easy. Sometimes things can annoy people for very random reasons. It would be hard for us to understand the reasons why you thought these things but it would be very hard for you to understand the reasons we think some things. I would say to try and get some of you favorite food and try to get an appetite for food going. Try to eat health but counting calories can get a bit hectic.
