Will I ever be happy?

I’ve had depression for almost a year and it keeps getting worse. It all happened when my classmate raped me, my school is full of assholes, and nobody understands me. Everyone always tells me that I’m annoying for wanting “to have everything” but really I’m just trying to make everybody in my school know that they need to stop acting like 2 year old assholes and realize that they are making me and my friends suicidal. I’ve already been in a mental hospital twice and it hasn’t helped. What do I do?
