My mother is driving me absolutely insane with her pessimism. I'm trying to be as supportive as possible, but she can turn a conversation about the sky being blue or my brother's wedding into "what did I do wrong to deserve this? why does everything bad happen to me?" and it is incredibly emotionally draining and manipulative. My brother and I are not allowed to have emotions or life experience of our own, because my mom twists them around on us and says "it can't be that bad because it's not like what I'm going through." I understand she has stage IV colon cancer, I understand she's in pain, but she is just absolutely awful about everything and refuses to see a therapist. How can I get her to see reason and make her realize a therapist would be beneficial?
