Depression? -_-

It would be helpful if we knew exactly how you told your mom (I mean is your mom really just evil and she really just doesnt care about you?), and why she does not believe that you need to see someone about it.

Do you have a school counselor? Or a teacher you can go to?

I would not use the self-diagnosis approach, it is one of the least effective ways to persuade someone that you are serious and that you have a problem. Believe me, as psychology students we read through a lot of disorders and it seemed like all of us had something or the other. I’m not saying it is not true in your case, just that self-diagnosis is not an effective way of presenting your concerns. You need to just talk about how you’re feeling and how the feelings have started to interfere with your life.

Who cares what your mum says! if yoru depressed and you want help, you get that help! Just about every school has a school physcologist, please try talking to yours.
