Mom is a borderline personality and dad is dysfunctional, trying desparately to just breath right so she doesn't act out. My parents that treat me as their whipping board. How do I handle this? It's very hurtful and frustrating. As the only care giver I don't even have power of attorney for their medical care. This goes to my long distance brother who barely even calls once a month. Mom's cognition is failing and she is getting harder to handle. Dad just tip toes around so she won't act out. Please, I need some advice on how to handle this situation.
