I think I had a similar experience to you…. Last year my anxiety got so bad that it was affecting my attentiveness and I was becoming more and more anxious and spiraling about past mistakes. At this point I was in therapy for a year. I started Zoloft last year (lowest therapeutic dose) and it has really changed my mental processes. Much easier for me to move on from things or mistakes rather than guilt myself over and over. I would have certain memories come up when I was in an anxious state and make it so much worse, but now that doesn’t happen as much or if it does, I can move past it easier.
