School Stress

(Sry if it’s long)
I seriously have no idea what to do. I’m a huge procrastinator when it comes to homework, but I usually get a grip and get it done at some point. Tonight is different. I have a ton of stuff to do and i don’t feel like doing it at all. The stress of all of my classes is literally making me cry, but I can’t drop them or go into lower ones because my parents won’t let me and I have plans to go to college. At least I thought I did, but lately I just want to quit school. I’m sick of everything about it, and I don’t learn anything important. I care about my grades (straight A’s) and want to succeed but idk if I can at this point. I have no idea what to do (like I said earlier) and the teachers aren’t helpful when it comes to extending due dates. Should I just give up? Please reply with some advice, I’ve considered suicide this is getting so bad. I feel stuck and worthless, with no hope of getting better. I’ve just recently gotten over my depression, but this is making it come back.
