First off, big hugs to you! Sounds like you are in pain. Are you connected with a counselor at your school? If not, that’s step one.
My concern for you if you don’t have parent support in your transfer is finances. How will you pay for school? You need your parents to complete FASA for federal aid and you are too young to get loans on your own.
I’d also encourage you to think about what you can do to improve the situation at your current school. Are you getting involved in clubs and activities? Going to study groups, sports, arts?
While you may have wished to be at a different school, your parents aren’t in control of your happiness. They won’t “win” if you make your current school a positive experience.
And remember, college is really a means to an end for most students. It’s about taking what you learn and being successful afterwards. In how we you personally define success. Many people go to schools they don’t love. It’s OK to not be in love with where you are.
That said, if transferring makes the most sense, go for it, but please don’t go into debt to make that happen.
