Hi there,
I'm sorry to hear that. But I have some thoughts about your current situation, I don't think you need to drop out of school, you just need to take a break, not physically but mentally. 67 is a very high score and I agree with the user above that you don't need to care too much about this 56 because you are still a very good student.
If you think it's really too hard to ignore, I suggest asking your tutor why this score isn't very good, as well as giving you some feedback on your studies. And to give feedback to the university to request a change of tutor, the role of a tutor should be to help and encourage you, not to make you feel down.
I always believe that when you feel sad in life it means better days ahead, and I hope you do too.
