Me and my mom fight constantly?

For example today we are supposed to go to a funeral and she bitches to me about a cellphone that I did not even lose. I lose EVERYTHING and this usually is what starts our fighting is me losing stuff,not paying attention, being human, her having a cigarette fit, ect. I don't care what her problem is because it seems like she never cares what my problems are so why should I care about hers? She won't change and neither am I. She says I'm not responsible yet I do all my chores, I get to school and appointments on time and I do my home and school work so how is that being irresponsible. When I do have an issue she asks me what my my issue is and when I say it I either get yelled at or she says "I don't want to hear it!, I don't care! (if she is very mad at me) or sometimes just plain shut up" we constantly fight over stupid stuff and she complains that I don't have a job yet sits and collects social security. I hate fighting but I guess I will have to get used to it until I decide to move out.
