I look after my mum. She is alternately tearful and aggressive, and I realise this is part of what is wrong with her but I am finding it difficult to step back and not let it get to me. If I say something she doesn't agree with she will look at me as if I'm something she has just stepped in. If I call her or she calls me and I can't understand what she is trying to tell me she will put the phone down on me then I am left stewing over what I could have done differently. When we speak later it's as if nothing untoward had happened. The whole situation is causing problems in my marriage, and I really feel like piggy in the middle. I sometimes feel I could just walk away from everything.
