Well Yeah we all go through patches of it, and dealing with it a lot of the time depnends on the situation, and why u are depressed.
I know this sounds sooooooooo corny and stupid, but u just gotta try and look on the bright side of life y'know. Try n look to the good stuff, things of the future etc.
Focus on the people u love as well, and the people who love u. things'll get better.
Hope u come out of this real soon x Good Luck x
