How do you cope.

Idk lately I've been stressed out with exams and stuff. I feel like idk man. It affected my sleep and stress. but yk how do you all still maintain being sane? It's like idk I'm stressed out. 2 days after it's exam day. I'm also stressed out about some scholarship test that I'm about to take next year. I ain't smart just average I try to keep my gwa around 90+. I don't understand this subject man. I'm going nuts.

Ffs...
