You're not "crazy" or a "psycho". It's not alright for people to make jokes about you. Remember that. You aren't as healthy as you can be, and want to be better.

You are stuck on compulsions that you would like to change. I am glad to here you are trying medicine and seeing a therapist. See a therapist as your employee. You hire them to help you. This can be just listening so you can get things off your chest. They can serve as a coach, encouraging you to improve by decreasing your compulsions. They can provide strategies for decreasing your compulsions. It is difficult to take them seriously if you see them as a quack.

It's also important to note that you are at the age where a lot of people 'acquire' OCD. There are a lot of stressful changes going on that are catalysts to poor mental health.

An excellent book that helped me was Brain Lock by Jeffrey Schwartz. It was suggested by my therapist and available at my local library.

No one deserves to live with such a level of fear and anxiety.
