I feel trapped in my home. help?

I literally am allowed to do close to NOTHING. I get no freedom. I am 17 years old.. I bought myself a car that my mom only lets me drive to work and back in because the title is in her name bc im not old enough yet.. Im not allowed to go to friends houses. The only person she will let me hangout with is my boyfriend who treats me like **** and talks to me like im a dog and the only reason i stay with him is because he is my only ticket out of the house. My mom picks my friends for me and checks all my phone records. i have a secret boyfriend who i am head over heels in love with and he treats me like a princess. But the only problem is that we never get to see eeachother because my mom is so psycho. We sneak and talk on the phone from time to time. I work just about every day at a car dealership and im not allowed to keep any of my earnings and i only get them from my mom if i clean up and things like that. she takes all my pay checks. i also did very well in high school and graduated a year early at the age of 16. Im about to start college in september. I just want freedom and to live my life.. ive tried to kill myself 4 times this year just out of being miserable.. the only outlet i have is sleep. my mom is a DRILL SARGENT basically.. She is crazy, psycho, overprotective, ruthless, shameless, and mean. I hear about all of my friends going out all the time and having fun going to six flags and parties and things odf that nature.. i just want to be a teenager and i feel like a slave.. please help me to think of a way to escape this madness and live a regular life. .. i dont turn 18 for a whole nother year.. any tips/suggestions/ideas?????
