My father doesn’t give two cents about me. He thinks I need to get a job.
If I’d tell him about my illness he’d probably ignore me. He knows I’m mentally ill, he just doesn’t understand what’s wrong about me. He doesn’t even know what schizophrenia is.
Honestly, I am in exactly the same situation. Personally, I have little reasons to hate my mother, but I just do. With a passion. Of course I can come up with explanations, but to a normal person they wouldn’t sound reasonable or at least seem overly emotional.
+++ Maybe it’s just a strong sense of “I don’t deserve to suffer” combined with an easy target to shift blame towards, like a mother.
