Insane Writer's Block! Help! Questions

I'm experiencing some major writer's block. Every time I try to open up one of my story docs on my computer, my energy just drains and I just get really lethargic and sad.

How do you guys fight writer's block?

Music usually helps me but it's not this time. For the first time in my life I'm having trouble with plots too, how do you guys plot your stories? Do you just write them as you go? or do you write them out completely? If you write them out completely, how do you do so? (Like an example of the format would be great)

I usually have an endgame in mind and a file to keep facts straight but kind of just go where the characters take me.

I'm really struggling here guys, it's starting to make me a little depressed :/
