Need help asap!

Idk what's happening with me i fucked my physics paper and now chemistry. I did half of the theory nd was expecting direct questions I skipped oc i never understood a single topic in that chapter.Getting 18-19 in worst case nd 20-21 best case in physics. Idk Abt chemistry getting max 15-16 got set 3 nd attempted around 60 marks ques only 4/16 mcqs are right. Ik it's not possible that I can pass. I want to know what happens next will I have to repeat 12th or just compartment in July. Coz I don't wanna repeat. I can't do this I can't disappoint my parents anymore. I wanna end everything so badly but i don't hv any guts. I'll just give English nd maths paper nd will try to do better will they pass if other subjects are good enough. Coz I don't have any 6th subject there's no way that I can be saved. I'm so overwhelmed Idk what should I even say to my parents they are expecting soo much from me. I don't wanna repeat i don't want to take drop i just want to go college far from here is there any way it's possible then please say. Please don't ignore i really want to know if there is any way.
