What should I do with the lyrics I write?

I've written about 70 scraps of lyrics since April of 2009 (When I was a dim 12, near 13 year old), but not a single one has been made into a full song. I'm not good with any instrument and I'm not that great of a vocalist. I try imitating my favorite singers (Bjork, Siouxsie Sioux, Lisa Gerrard, Brendan Perry, Elizabeth Fraser), but it's always difficult...
