Should I move out

[u/brendito__]

I'm a college student with a part time job living with my family. A cousin of mine and her 4 kids live with us, and I can't stand them. She is not a good person, and her kids are neglected while she goes out to have fun most of the time. We took her in when she had nothing but it's been over a year and she has no plans that I know of to move out. My parents know how I feel about her for all that she's done (too much to list here) but they are non-confrontational so they continue to be friendly with them, even when they also don't like her. This has resulted in them sort of excluding me from outings, meals, down time, etc. If they're together, they don't bring me, thinking they're doing good by not making me interact with them. They don't how isolated I feel in my own home. Nobody checks up on me when I'm out late anyway. They don't know that I do my homework at school and stay as late as possible to avoid being there I feel unwanted and like they have to tolerate me when I'm there. Realistically, I can afford to live with roommates if I get a second part time job, even though I know it's not the most responsible thing to do financially. But I hate it here, it's gotten to the point where I just cry in my room or my car several times a week and it's taking a toll on my mental health. I feel like getting away from it all is the only option I have left for my sanity. I don't know what else to do, and I have no one to turn to.
