I am in bits at the moment because my rocky relationship with my mother has just hit another bump. If I'm honest, it's barely anything, she invited her brother into our family home (having said she wouldn't after he sent me a whole load of abusive emails) and I don't even live there anymore. I feel as though, like everything that happens she makes it my fault (abusive emails were as a result of me inviting him to a Christmas party) and that by being upset that she has welcomed him back into the fold I am being unreasonable. I really don't know what to do about it, it seems that whatever I do (such as host above mentioned Christmas party)I am in the wrong and am ostracised/pushed out for, but my younger sister can steal, lie, cheat, get fired and her behaviour is explained as other people's - usually my - fault and excused.
Is there anyway to stop feeling so undervalued/invalidated? Can I have a relationship going forward? I don't know what to do at the moment.
