I'm so sorry you are hurting, and anyone else out there in the same situation. I reached my limit with my Mum about 5 years ago, and severed all contact, my life has been so much less stressful without her in it. BUT, that's just me, you need to look inside yourself, and see where your limits are, the effects she has on you and your everyday life, and if you think it will ever improve, only then can you decide the best course of action for yourself. I wish you all the strength you need for whatever choices you make.
