I'm having a hell of a time with rumination and repeatedly going over the past. I'm so angry about it, that I feel pretty bad because I've been angry for so long (coming up on 24 hrs straight) that it's physically exhausting. I can distract myself for a moment or two, and then it comes back, "They should have done X; should not have done Y!!!" ranting the same things over and over in my head. I write it down to try and get the thoughts out of my head but I have written the same screed I think 3 times now. I'm better for about an hour, and then, "OMG they hurt me so much!" Not exactly a pity party, more like a resentment party. Worst part is I blame myself for not knowing better, and I was not in a good frame of mind at the time I made the mistake, so it's complicated.
It brought up some old trauma memories and emotional experiences that I wasn't ready to deal with. Or, maybe I was and that's why the universe put me in that position? My therapist has said that our "stuff" comes up when the body thinks it's ready, not when I feel it fits into my schedule. But it's goddam hard and I'm bugging the hell out of my recovery friends because it's practically driving me to relapse.
