Jorge, My heart really goes out to you. I didn't tell my parents I was a girl until I was living fully on my own having been educated and having achieved independence as a guy. They might have had a similar reaction. I know the pain must be severe, and it might feel like there are no solutions, but there are.
Jamie is right about college. It is the best path for getting the care you need and the education that will help you succeed as a woman. I'm no expert in college admissions, but may I suggest that you go and talk to an admissions counselor at a college that you might like to attend? You might need to tell them everything, but you should at least tell them that you have no parental support. I won't promise anything, but you may qualify for Pell grants, and the college might have you declared independent of your parents, which would qualify you for financial aid based on your income instead of theirs. Sometimes that's a big difference.
If the college has dorms, you would basically have food and shelter, in addition to a qualified counselor and medical staff, who might be able to help monitor your care.
As trans-women, our lives require us to be brave. You should appreciate the bravery you've already shown. Now, it's time to direct that bravery in smart ways by taking advantage of the best options available to you.
You can do this.
Jane
