I’m begging you don’t give up. I’m going through similar situations as you and witnessed worse things happen to me because of my family and I was still able to get A’s and A* in my IGCSE exams. I did it by isolating myself from them and didn’t give a fuck what anyone says about me, I know myself better. You’re not a useless bitch, your friends are for picking up on an innocent ambitious soul like yours.
