What should i do? Run stay? What?

All you can do is try to do the best you can. So what if you didn't get what you usually do it's not uncommon to be perfectly shining through your grades an your parents need to accept that. I think that they are expecting to much from you, an they are ignoring you ? It must not be very comfortable right now at your house. But they should be ashamed of themselves for this. it's not them taking the tests its not them studying for it an its not them who has got the good grades in your exams before. Don't cry to sleep as long as YOU know you did the best you possibly could have. Thats all you need. Maybe you should tell them how you feel.
