No good ideas here, sorry. Maybe go dance on a bar somewhere – it seems to help sometimes. 
But I feel your pain, and I really hope that whatever it is that has you bummed resolves itself into something better. There’s too much misery among the Teeming Millions, and you don’t deserve to have part of it.
Of course, there’s Bluto Blutarsky’s classic suggestion: “My advice to you, is to start drinking heavily.” It may not actually help anything, but it makes bar-dancing come that much more easily.
