Writers block!

I am in the middle of writing my senior writing project. I need 20 and have written 15. Things were going great. I was writing well. But now I am not. Everything I put down seems wrong, or does not give me any feeling of rightness. When it's good I can feel it, I let the words drip out of me and before I know it, I have something grate. But what I am adding now does not feel that way. I need to jazz things up. I can't let this story die on me. Not now not ever!
