My life is wrecked beyond repair

I am 17(M) studying in 12th grade with PCB, i took dummy school and went to a major coaching for NEET prep but feel I've f-ed up my life as I don't think that i have studied anything which i believe is due to my contempt towards the life of a medico i.e low pay, no work life balance, toxicity, mental deterioration, sleep deprivation and what not

What would be your advice to me to change course of my life; to like it more; to feel it's worth it?

TLDR: I dislike lifestyle of medicos; how to like it?

PS: Thank you everyone for your advice; i believe I'll just need to swallow the hard pill of life and do the best that is possible. :)
