Sexual abuse flashbacks. Please help.

I am a college student .Recently after watching a movie,suddenly I had flashbacks of sexual abuse when I was a 7 /8 years child.Then other memories of my childhood started flooding me like when my friends where playing Doctor,and I knew the whole process or when I tried to act out due to arousal but somehow I stopped myself cuz I felt that was wrong.I was very enraged during my childhood and sometimes got so angry that it seemed I could harm someone.But then I grew busy in school,these traits started lessening,and I became calm and my sexual arousals became very normal.But all these memories,these flashbacks have deeply frightened me.I fear that if suddenly those urges come back,if I may harm someone because in that movie it showed that child sexual abuse victims are more likely to sexually abuse in future.Also I have OCD prblems.So my brain cannot make out a thing.Even the thought of harming a child repulses me,but I fear too much.I cannot even go near a child or animal.Please help.
