Hang in there, Mimic. It does get better. I am 2 1/2 months out of my marriage and my RAH continues to get better (slowly) each day with the help of AA, but the separation saved my sanity. The first month sucked - the second month was much better and the last two weeks I feel like my old self again! Life is good again. Oh, I still have bad days or bad moments, but I am in a much better frame of mind to deal with that when it occurs.
It will only get better from here. Stay strong!
