Moving forward

First time fallen in love ever n the flashbacks r so bad. Have always been sexually active. 1 night stands n stuff but never with som1 i care for. How do function?

It sounds as if your flashbacks might be partly triggered by feeling a strong emotional response to the person you love. This would make sense if you felt a strong emotional response (negative or positive) as part of your previous experiences that you are having flashbacks of.

Have you considered seeking any professional help in order to help resolve some of these effects from your experiences?
