Kicked out

I’m 21 and on Sunday I found something out and I tried to talking about it with my parents but they want to act like I’m crazy and wigging out for no reason. I was freaking out so I called my best friend to come pick me up and my mom wouldn’t let me leave but I ended up leaving anyway. She was gripping my arm and yanking on it but I kept pulling away telling her to stop and let me go. I stayed the night at my friend’s place and his roommates didn’t mind. I came back home yesterday and begged my mom to let me come back. I have 3 little brothers that I love more than anything and I don’t want to leave them. I don’t really care for my parents anymore at this point, it’s just the kids. I always take care of them ever since they were born. My mom had my first brother when I was 10 so she expected me to help and I didn’t mind because I was so excited but it’s to the point where I’m basically a live in nanny. I wake up at 6 am everyday and get them ready for school. I get them to brush their teeth, put their clothes on, tie their shoes, comb their hair, make sure their homework is in their backpacks, put a snack and water bottle. I go to the parent teacher meetings, go eat lunch with them when I can. Take them to bus stop, pick them up from bus stop. Do homework with them and the projects too. Make cupcakes for their class on birthday, get gifts for teachers on their birthdays and Christmas, volunteer. I basically do everything. I also have a job and I haven’t been in school for the past semester. My grandfather passed away in March and my mom loves to remind me that she couldn’t go but I went to Mexico twice to see him. Once while he was sick and for the funeral. She acts like I don’t know what it’s like to lose a dad when my first step dad that I considered my father passed away in March of last year as well. When he passed she acted like it affected her so much but it was just an act. She cheated on him and left him for my current step dad 16 years ago. I have no savings because I always spend money on my brothers, I pay my phone bill and my mom’s. I also don’t have a car, my grandpa gave me $5000 when I was younger to get a car or for college but my mom and step dad decided they were entitled to it because they paid for all my food, clothes etc. My step dad had a car he was going to give to me but when his nephew moved in with us he let him “buy” it from him and he just paid it monthly til he got it towed and couldn’t get it back. So I have to find a place to live in the next month or two, get a car and a better job because the one I’m at now pays a little less than $10 an hour and I only get about 25 hours a week. What do I do? I’ve considered working on a cruise ship to save money while I work there to save money since they pay for your room and board. I just don’t know what I’m going to do because I have no money.

*EDIT*

I’m not sure if enrolling in school is an option at the moment. I failed 2 semesters due to leaving mid semester to take care of my dad who was sick and eventually died as I stated above and the second time when my grandfather was sick. I was put on academic suspension at my community college. Would I be able to enroll at a regular university without having to transfer?
