Am I crazy? Am I delusional? I can't stand my mother. Her crazy antics are driving me insane... so wait, am I?

I can tell you that I'd have cut your mother out of my life years ago, but that's based on my personality and experience. You have to do what seems right to you. I think you've really gone out of your way to help your mother, and she doesn't appreciate either you or your help. How much more of her abuse can you handle? I'd say just get her out of your life by whatever means necessary......but that's entirely MY opinion.
