Im going insane?

I think i might have ocd, I get these thoughts that seem to never leave me alone. I first started having this problem about 5 years ago when i found that i was aware of breathing and i would constantly control my breathing, but then after a few months it ped and I went back to my normal self for a few years. but then in about 5th grade it bothered me again but it was controlling my swallowing and i felt the urge to swallow the smallest amount of saliva in the back of my throat. I remember feeling very depressed and distracted... my grades dropped... it ped after a few months and now years later i get these impulsive thoughts of every little thing like if i dont make a lightswitch click when i turn it off i have to do it again. and somtimes i get crazy aggressive thoughts... I am currently 14.. how can i get this to p without meds or a doc...i tried a doc and it didint help..
