I haven't found it necessary to barf up much more of the past. I'm in a good spot right now. I still have rumination daily, but it isn't severe, and sometimes I barely even notice it. I can feel myself getting better.
I know reflecting on the failure of a relationship is a natural and necessary part of healing. The only way I could get past the pain and suffering, depression and anxiety, is to go beyond the criticism of another person's behavior and general persona. Reflecting on specific events and qualities must have some usefulness, otherwise we wouldn't do it, however, if it becomes prolonged it isn't healthy.
At a little over ten months, I've come a long way. I'm happy more than I'm not. I can add happiness to my gratitude list. I'm alone and happy. I am happy with myself.
Good stuff Perfidy - thanks for sharing!
