I'm always afraid of making mistakes. I have this belief that every single potential mistake I make will be catastrophic. I'm always tense and on edge, being extremely careful with everything I do. I also keep combing through my thoughts, thinking about past events to try to identify junctures in time in which I made an error. I think that if I can identify a mistake in the past, I can act to minimize its consequences. 

I just get caught up in this line of thinking all the time. Sometimes my mind just picks negative events/experiences that happened years ago and I'll just shut down and worry about it, replaying it in my head over and over. I'll think about what I did, or what someone said to me, and such. I know it's irrational but I feel so anxious that I've messed up somewhere and that bad things will happen. Anyone else ruminate like this?
