My grandma moved in and has dementia. I'm mentally ill. I try to distant myself sometimes because I can't handle it all the time. Basically when I tried to explain this to my mom and stepdad they don't understand. My stepdad blew up, told me I'm being petty, to get a grip and he doesn't want to hear it anymore. I said I was trying to apologize. I said I don't want you to think I'm a horrible person. He said too late. I'm already really hard on myself. I feel like a horrible person. My mom doesn't back me up either. I'm tired of trying to make them understand.
