What should I do?

I was a consistent honor student and my parents always think it was little and I practically give up in trying my best because they never told me I did great, now I'm a shs student and I failed 2 or maybe more subjects. I felt so worthless and I don't know what to do anymore, it's my first time crying because of failing. When me and my mother fight she always retort to my grades. I just accept it cause it's true that I'm a failure and I'm dumb, I'm not what I used to be and I feel like giving up already. I felt too pressured because I never experienced this back then so why now? can you please guide me? I don't have someone to talk to and I'm super embarrassed of myself.
