I have had OCD for years now and it recently took a switch to hit and run OCD and has been on and off for a year now. I keep going back and trying to analyze what happened this one night a year ago. I keep thinking of these thoughts of or details of what could of happened and I all of a sudden will have this thought or image and think wait I remember that! (So i think) and then I start freaking out thinking oh my gosh that's what happened and the process just keeps repeating over and over until I have all this evidence and these memories and feelings that I think really happened and I just go into a total panic attack. Is this OCD or real memories? It's almost Christmas all I want to do is enjoy it with my family. Holidays aren't fun with panic attacks.
