Hello pinkvilla: Well... I don't have any great suggestions for how to deal with this type of situation. I wish I did because this is something I struggle with 24 / 7. And, like you, it's at its worst in the morning. The only difference is that, in my case, the past mistakes I perseverate over are serious ones. On the other hand, they all occurred many years ago now. And continuing to beat myself up over them really accomplishes nothing. Yet even though I know that, I still cannot let any of them go.

I don't know if this sort of thing is considered to be OCD. My view tends to be that pathways get worn into our brains over time. And thoughts just keep running down these same old pathways... sort-of like a car that can't drive out of a rut in the street. I suppose there are medications that might help with this perhaps. I don't know. I'm not on any med's & I don't see a therapist either. What I strive to do is to simply accept the thoughts I have... with compassion. I try to allow them to come up, breathe into them, maybe even smile to them, & then let them fade out at their own pace. It's a Buddhist practice called "compassionate abiding." It's not a cure. But it's what I have to work with.
