I failed my 10th ka exam today.

Idk what to say at this point.. I just came back.. max to max I'll get 20-25 marks from theory.. pass toh hojaunga.. school says 85% in both maths and science for PCB stream.. meri hamesha se dream thi ki i would do medical n all.. but.. now I don't think school stream dega.. all my life I've studied in this one school, I can't change it. I just want to die.. and not bear this regret of not studying. Please. What do I do..
