Thank you all for your responses. I just have certain instances where I replay in my head- like you said with the funeral memory- and wish I did things differently. I can relive the moment the only problem is I cannot change it so reliving does not help me it only makes me anxious and wish I can change it. So this vicious cycle forms where all I get is guilt and anxiety. Many of these memories are from 2 years or more in the past. I have too vivid of a memory and I hate it! I really remember almost every detail in a sense. After about 5 years one of these memories stopped haunting me. I guess I did finally let it go or like you said realize it was not worth it. I just cannot wait until it won't happen at all.
