Is it normal school, my mom, my brother

Is it normal my mom feels this way? Im not doing that well in school, and i haven't been for a couple of years. The depression i feel i believe contributes to how i do in school but my mom doesnt really seem to listen. Often times i try to study and i cant focus or i totally lose motivation. Its similar to how i feel everyday how i say, "todays going to be different." and then its shitty as always.

she says how my brother whom has/had aspbergers is doing better in the classes i took and that i should be doing better because he can do better. Personally im thinking of just giving up and not looking back. i try but she doesnt seem to care enough to think about how that could be the problem.. and even if she did she only thinks her way is right.
