I think my mother is going through pre menopause or something?

My mother is being a complete *****. I graduate from high school in exactly one week and she's already screaming at me about finding a job and stuff. I already told her and my dad that I'm planning to. But she just won't shut up. She's INSANE. She screams and insults me all of the time just because I don't pick up around the house. I'm going to college in the fall and I don't know how I'm going to deal with her all summer. Any advice?
