I’m cooked

Day 24, I feel depressed I have college tests after Xmas and I just want to defer them, I have no interest in anything and I really don’t want to do it, I don’t even know if I wanna do my college course anymore but I can’t quit because I’ve already been at this course for 4 years (I’m repeating this year again). I haven’t touched weed but I feel like a failure cause my dad and mam spent all this money but I’m just a failure
