I believe you are entitled to every emotion you are feeling at this time. And I agree that now is the time to be working on YOU.
I was never so stressed out and angry, and crazy as i was when I was living with an active alkie. It sucked the life right out of me, and at times I forgot how to breathe. So by all means, learn to breathe again, just for you. Embrace you, tomorrow will take care of itself.
May you find peace as you travel this unknown path.
