Ok, you are getting crap cause you got B's.. are B's the best you can do?
I ask because VeggieFrog got in a world of trouble on the odd occasion she got a B. Why?... because she was capable of better. If B's were the best she could do then i would be happy and proud of every B she got. But for some kids... well, a B+ to VeggieFrog was like a C- to most other kids. So yea... B's were a big deal.
More serious than the bad grades, however, is the fact that you think it is an option that you can get into your parents email accounts and hide the grades. That is seriously messed up. That, to most parents, is a more grave problem than bad grades.
And here are a few serious questions...
How old are you?
Do you have a job?
If they packed your stuff and put you out, could you support yourself?
What do you mean 'fight'? Like you are an equal and stand on equal ground in what goes on?
