Okay, fine, that's okay.
So I decided to take what I could from this experience and move on. It's been three months since I saw her last, a little over two months since we communicated. Now, people say not to overanalyze situations, advice that has served me well in the past and calmed me down. However, I've gotten advice, on this site particularly, to think about the experience I had with her and analyze what I did wrong or right and improve on them for next time.
The problem is, every day I still think about the memories and analyze them, and I've been doing this ever since I last saw her (three months ago) to the point where now it seems like I did everything wrong with her. Now it seems like every interaction I've had with her there was a mistake on my part and that's breeding more negativity and I get angry at myself. It's to the point where there's no happy or good memories, just excruciating ones.
In other words, it's gotten to the point where acknowledging the fact I made mistakes (real or imaginary) is painful in and of itself.
Can someone help me to just "not worry" about everything? I've analyzed so much that now I'm not SURE it's over, even though I well knew that a few months ago. I'm questioning everything.
