I'm 17 years old boy. I think I have obsessive compulsive disorder. Whenever I have a thought of some unpleasant memory, I always want to wash hands, and then I want to do it again and again. I can't resist myself from washing hand. I cannot concentrated on my work until I don't wash my hands. Also at night, I check my door 20 times before sleeping. I check my fridge, gas stove and my important things several times everyday.
If someone abuses me or shout at me, I continuously keep thinking about it. And I am really too afraid of germs, I wash hands after touching everything, even after combing my hair or touching a paper.
How do I become normal?
