the mother ~ daughter relationship must be the most complex in the world in my opinion.
It's okay to take some space from it.
My daughter is wanting some space from me at the moment...this is not the first time she has been mad at me.....and I just know that she has her own life to live and she knows that I love her. We just disagree pretty strongly about a couple of things.
I have done the same with my mother....been so terribly angry, went to counseling, limited contact and etc .....but now we are closer than we had ever been.
And all this and drugs/drink are not even an issue!
Therefore I hesitate to make any suggestions!
But I do want to tell you that you do deserve your peace of mind, and your private space.
