Is it normal to seriously resent a sick family member?
My grandmother has been living with my mother and I since I've been very young and though we've never really gotten along, I never really hatred her. However, that changed when she ended up getting cancer six years ago. Ever since then, my mom and I have been her caretakers (My mother admittedly more than I.) She's also become just plain psychotic and hysterical.
She consistently needles at me with the few things she knows hurt me the most, like my weight and my long and frustrating struggle with depression. She constantly throws my mother's money troubles in her face, despite the fact that my mother's job is one of the few things that allows her to actively take care of her, since she can't take care of herself. She always talks about how much she love love loves my aunt, even though the woman can't even be bothered to take care of her own mother because she can't handle the drama that comes with the care a sick person needs.
By the time I turned 16, I just got so tired of dealing with her on top of all the crap I used to get in my day to day school life that I decided to be an idiot and attempt suicide. Obviously, I lived, but I was nearly put in a mental facility and needed to take about a week to fully get my body in working shape again. When I got home, she lectured me for hours on how embaressing and disgraceful I was for the family and that it was me who ended up causing her to have cancer.
I know that it's not easy to have cancer. I know that she probably has a right to be so upset, since nothing ever gets better for her, but I just can't stand her anymore. Seeing her makes me so mad that I just want to scream in her face until she feels like I feel when she treats me like garbage. There even is a small part of me that wishes that she would just go away and I would never see her again. I don't want her to die or anything, as she is my grandmother and a part of me still loves her, but I just hate her so much sometimes and I feel so horrible about it.
TL;DR I have a grandmother with cancer who treats me and my mother like trash. Is it normal to seriously resent her?
