My mom has ms and i dont care?

She is an awful person and an alcoholic. She makes fun of me constantly and gets in the way of all my goals. For example, I wanted to start recycling and she called me gay and told me i wouldn't make more then 5 dollars doing it. Another example is my attempt to lose weight to my efforts she only buys fatty foods for me and calls me a dumb for wanting to lose weight. The only thing she talks about is herself and never asks me how my day is. She gives me money and thinks its the only thing a parent should do. She seems to like the attention and tells random people about her hospital visits. Its pathetic. I just want her to not be in my life anymore. So my question is: am i a bad person for not showing her sympathy? Suggestions?
