Punkin, I had stress related excema just prior to the first divorce hearing, [which took place, but we had an adjournment, which is a book in itself!] Like you I felt a failure initially, but thre months post divorce, while i am still dealing with some sadness and loss at the waste, I actually feel great most of the time. I requested very nicely to my xh that we have no further contact, and he has respected that, which helps.
Apparently he is depressed!! Well he got what he wanted, and it seems we need to be careful what we wish for. I am not saying it is easy, but you will find reserves of strength because you are dealing with everything as it arises, and acknowledging it fully. I admire you greatly
