Jesus people!
What happened to exploring college I believe you said you were interested in culinary school?? Look that might not be an option right off the bat but college itself is. Even if you don't want to do anything but cook, get your degree in General Sciences. It's what many people do until they find out what it is they do want to do. The semester has probably started now but you should at LEAST fill out the FAFSA. I know a few people, myself included, linked the FAFSA info for you in the other thread. It may not be your dream plan but it certainly sounds better than your other options. Do it now, even if you can't start this semester, that way everything will be in line for next semester. With grants (which it sounds like you will easily qualify for) and loans you can exist for at least the next 3-4 years with a much more promising future than pretty much any other realistic option. At least that way you only have to worry about getting by until the school semester starts.
Really, if you don't do this, I seriously will not believe you wish to change your life for the better at all before being forced to do something you don't want to by other people who shouldn't have any say so in what you decide to do with your life. File FAFSA, find some bullshit job (ANY job) you only have to endure for the next 6 months or so until school starts. Don't tell the new employer that's your plan or nobody will hire you. Look out for yourself and don't worry about the job/boss you'll be leaving. If it came down to it, they would have no qualms about screwing you for their own well-being. Do you not have a friend that might let you stay with them for the time being? If not, as others have stated, go to seek whatever programs the government has for you. Tell them the situation. There are answers, you just have to seek them out.
Also, when you apply for financial aid, do whatever you can to claim your parents are not supporting you at all, even if that means claiming abuse, it's not like they're giving you much choice and frankly, the shit they're doing with you could qualify as terror tactics. Have they even mentioned college as a possibility?? I don't get parents like that. Although I am pretty sure you're going to qualify for everything out there. It doesn't sound like your parents are in an income bracket that would disqualify you for aid.
Do what you want, but if I were in your shoes, knowing what I know now, well, I'd do the above. Good luck and stop putting it off!
