Sounds like your parents do not understand mental illness, I bet they think you are just being lazy. Maybe you could have your therapist talk with them. Screaming will get you no where as I am sure you found out. School is important and as you start your last year of high school you need enjoy it as you will not be there again but at the same time your parents probably want you to take on some responsibility with a part time job, like paying for your own gas for car and ins. I kinda see where you both are coming from there is just a real lack of communication that you both will have to work on maybe with some outside help you can both come to a happy medium. I wish you the best.
