Help me eat and cover loans!

Hey! Call me Liz. I'm a queer mentally ill girl struggling with post-college life and an abusive family. After taking an extra year at college and working hard to complete my graduation requirements, I still wasn't able to earn my degree. My parents cut off my driver's education years ago, and despite job hunting efforts, I haven't been able to find employment. I have a little money, but I'll need to spend it on student loan payments. I submitted an Income-Driven Repayment form for my federal loans, and when the current administration stopped accepting those forms, they froze the loans so I won't have to make payments. However, in the meantime, I also have private loan payments. I've contacted them to retroactively apply a forbearance to my overdue payments, but those payments will resume going forward. Thanks to some generous donations, I've been able to make a dent in June's payment, but I still need $600 to make up the rest. Anything over that would still be wonderful, as I have next month's payment to worry about and so on.

In addition, my living situation right now is dreadful, and I'd like to be able to buy some groceries. My parents are letting me stay with them for now, but they've been refusing to provide me with enough food. There's plenty of food in the house, but I have to ask permission to eat any of it besides instant ramen, and occasionally some bagels, biscuits, wafers, or whatever leftovers my parents don't want anymore. There's no health reason for this restriction. It was imposed as a punishment for not cooking my mom some rice back in January, when she wanted some to go with a meal, but didn't tell me. Since this rationing started, I've lost a truly concerning amount of weight, to the extent that I can see my own ribs and hip bones easily without much stretching. I'm eager to pick up some shelf-stable foods I can keep in my room, so I'll have a guaranteed source of nutrition.

My parents have always been extremely hostile to me, and in the past they've repeatedly threatened to kick me out. That isn't really an option where we live, because I have no income and there are pretty much no shelters in our area. My parents claim they don't want to kick me out, primarily because it would make them feel like jerks, but they still go out of their way to make my life miserable for no apparent reason. These are people who would punish me when I was little by hitting me, depriving me of food, and confining me to my room for days. They've mellowed out a little over time, but even in the more recent past, they've pulled stunts like cutting off my access to the family credit card to spite me when I needed food (they still haven't undone this) and threatening to call the cops on me if I came to their place. Living with them is near unbearable, due to overwhelming verbal abuse, aggression, and coercive/controlling behavior.
