Great advice here!
Use the next few years to do as well as possible in school. Talk to your guidance counselor now, tell her your family situation and that you have no support for going to college. She will give you good advice on how to proceed.
If you don't have a job, get one. This will give you time away from family, and save at least half of your money towards college.
what are you passionate about? Pursue it, and see if there are any community programs similar. Try to make new friends.
You can get out of this small pond you've been brought up in, you just need to go slowly. Don't feel desperate. You're going to be ok.
