My 79 year old mother is sometimes mean towards me. She doesn't trust me. Why do I feel guilty when I get angry towards her for treating me this way. I have out my life in hold to care for her and to keep her in her home. She's not an invalid but the verbal and emotional things I'm allowing her to put me through is killing me. I keep hearing don't internalize her behavior and I'm working on detaching but it's hard to keep up that practice. Any tips?
