I can stop giving my family attitude especially my mom. Every time I come home from college break I'm miserable around them. I argue with them all the time. Now my ill grandmother lives with us and I get annoyed everytime she asks me questions or asks me to do tasks for her. I'm very mean and depressed around my SO. I feel like I'm just a miserable person and that they would be better without me in their lives. I want to change but I keep reverting to the same old ways and attitude. I know my family is waiting for me to leave. They all get along but when I'm in the house there is only tension.

Advice please
