How am I supposed to manage my time with school and work when my relatives are in town?

I just found out that my cousin (that I’m not fond of) is in town. Nobody said a damn thing. My dad called and straight up asked what I was doing and I said homework. Then he said my cousin is in town and the family is going to be there and asked if I wanted to go. I reluctantly said sure since my family will wonder why I didn’t come. Always happens when I don’t come or show up. Anyways I have a lot of homework assignments this week and I work 40 hours of the week. If it was holiday break then I wouldn’t mind.
My cousin gave me HELL when we were kids. I never liked it when she came in to town. She bullied me and played with me roughly since I needed to “toughen up”. I’m autistic and I can be timid. Well used to be. I’m always the butt of every joke she made.
