What should I do?

I’m totally lost right now. I’m 18 almost 19, in college, completely broke, and I need to escape. I don’t know what to do…this may seem like a bit of a rant, but I have no one else I can talk to…sorry in advance. My family doesn’t appreciate anything I do…I work my butt off and I get no “thanks…” I just get yelled at and told by my twin sister, that I shouldn’t live here anymore. Like today, I go to class early in the morning and come home late afternoon, I’m starving and come home and the kitchen is dirty, I mean dirty. Dishes everywhere, garbage everywhere, and I walk down the hall to take my mom mail and her and my sister, who are home all day everyday, are doing NOTHING! The least one of them could do is clean the kitchen! I mean this happens all the freakin time! They do nothing and I’m stuck cleaning up their crap without a single “thank you” but all I get in return is I’m a psycho, I’m a cow, I don’t deserve this and that…you know stuff like that. Then my sister went into the kitchen, while I was cleaning it btw, and starting cooking! with the things I just cleaned…and on top of that, she left a mess. She only made food for her and my mother…I don’t understand why they treat me like this. Is it ok for me to feel upset about this? I need to get out, but I’m a full time student and don’t have time for a job, but I’m going to get one, I need the money so that I can make my own living. I have a really good boyfriend, he said I could stay with him for a few days…but I don’t know what I should do… I feel…lost.
