I'm afraid I have no good advice to give. But I can offer you support!
I am here going on 7 months of WAH for OW. OMG--I can't believe I just typed out 7 months. It has been long and hard, but each day is better.
For me, the best thing was keeping as busy busy busy as possible. Running helped an awful lot. It helps my mind, helped my body (down 30 pounds, but that was mostly not eating from anxiety in the first 2 months) and has helped to make a few new acquaintances.
I also went right to my doc for anti-d and anti-anxiety meds, which have helped a lot.
I, too, felt--maybe still feel a little?-ashamed. And maybe now I am getting angry enough to say--why should I feel ashamed? what have I done? He chose to start an affair and just end our R without so much as a how-do-you-do.
So I understand the ashamed feeling, but want to reassure you that will fade. You have done nothing wrong. You ARE good enough. You are BETTER than good enough.
Lean on your friends, and GAL all you can.
Aver. I still feel ashamed with certain groups of people. I know its ill-rational.
But I have cut out a few groups of mutural friends and I have stayed away from some gatherings with work people.
Flowers always make people better, happier, and more helpful; they are sunshine, food and medicine for the soul. unconditional love is awesome!
