i kinda just want to die

a couple months ago my mom let me use her old car because she got a new one. she said i can use it to get to work and back but i began using it to get to school instead of the bus because im a senior and dont need as many classes. i also used it to get home from practice and she knew she kinda didnt hassle me about it. yesterday i took it too far and drove 40 minutes away and she took my keys. it may seem dramatic but i kinda feel no reason to live anymore. things like going to practice and driving to the gym kept me sane so without these things i dont know what to do. she said i need to buy my own car even though she has 0 use of the old car. i also cant buy my own car because she wont let me put a down payment down and i have no money saved and ill lose my job if i have no way to get there. please send me solutions because im losing my mind.
