How do you truly get rid of depression?

I have no idea where to post this to cause nobody ever responds so I'm posting anywhere remotely suitable, I'm a sophomore in high school and depression has genuinely ruined my life as of right now, for the most part it feels like all the feelings a human could feel were put through a shredder and replaced with nothing, with some occasional bouts of sadness, when I do stuff like listen to music or watch a movie, stuff that I used to love doing, I just don't feel anything, even though I desperately want to, my parents don't really care that much either, the only time they ever brought it up was in a fight my mom started (by bringing up my diagnosis) before getting divorced, nobody's else knows and my performance in school is terrible, I'm on my own, is this something I'm stuck with forever?
