Hi, you totally have my prayers. I don't know how to help other than that, so hopefully this is ok. (sends e-hug) You'll get through this somehow.
If you're dad won't leave you alone, can you take any kind of legal action? A restraining order something or will that make it worse? You deserve better than this!
Can anyone one at you're church act as something of a father figure? Maybe going to see you perform in a play of something like that at least?
For college, if it is hard for your mom to make enough, then you should be able to get financial aid. It sounds like the college might really want you to go there if they are accepting you as a tenth grader. To get the financial aid that you should get, you might need some way demonstrating that your father isn't helping, but this sounds doable. Financial need is also considered in scholarships. Fastweb.com is a scholarship search site. Try searching there and sending a few places the required essays. (This might be easiest before you start college.) It's worth a try. Financial aid offices may also have people who can help you find scolarships. Try to keep you gpa above 3.0 if you can. This is the most common gpa requirement, but if you can't, there are still scholarshps that you can apply for. My family's auto insurance offers a "good student discount" as well as a good driver discount for students with a 3.0 or higher. I found that I did best taking 12 units instead of 16. This also gives more time for a part time job or something. Many colleges have part time jobs available with hours that you can work around classes. I don't know how close you live to the campus, but consider where you will live. At some Cal States, a student living in the dorms will pay as much for housing as they wil for other stuff.
