I do the same thing. I relive decades old social interactions. It sometimes does my head in. "I could have done this, should have said that, why did they say that, why did they act that way towards me", etc. It's usually around something negative, something angsty. I've been slightly paranoid as long as I can remember, so that plays into it. It can be insidious. keep looking for ways to get a handle on your issue, Chindie, i know you can do it. It just sounds like you are in a deep funk but you can manage with help. I'm taking a small dose of Lexapro daily and I also take Neurontin when I feel like I need augmentation. It's a very effective drug with multiple uses. I should really try CBT as well, I'm sure it will help. i just hate talking about it, so I need to get over that.
