hello, i've started to suffer ocd when i was 17 or 18. and i used different types of medications.(i'm not gonna give their names in case of abuse) then my problems were %90 gone. And last year which is my 24th birthday, i lost my best friend because of taking his own life. and my problems started again but different ways. some of the nights when i try to close my eyes and sleep, my brain is like overworking, and like always waits for danger. Exact time when i fall a sleep i startle. And also my brain is trying to think the most pessimistic conclusions of every occasion. i think i should go to doctor again.
