If you wanna go with that depression, The hours. If you wanna snap out of it Shaun of the Dead
Animal House. Lillies of the field,
American Pie, got the box set, they cheer me up. Plus King frat.
Silver linings playbook, i love this movie, it always gives me hope. And Marley and me.
Austin Powers. Hot Shots. Ace Ventura Pet Detective. Wayne's World. Old School :)
Like depressing movies?
The perks of being a wallflower?
I find books and read them though usually, things like: by the time you read this I'll be dead, thirteen reasons why, hold still etc.
Hope this helps!
Suicide Room, The Perks of Being a Wallflower, Chatroom and Black Swan are my personal favourites. Third Star is rather depressing too, but it doesnt really deal with cutting and depression, mostly cancer, suicide, and strained friendships, its really good too.
