Writers block

Ok. So WTF! I try to write and just can't! Its driving me nuts. Cause I have the will too, and I know what I want to write about, but I just can't. For example I met this really cool girl the other night. We talked and talked and I had such a good time. I know I want to write something about her, using her as my muse I suppose, and I KNOW that it should work, cause I can feel the words, but I just can't write them They seem to die on the key board, or once they hit a page. I don't know what to do about it but I am going to keep trying a wait until this block dissolves. Maybe I just need to actualy experience those emotions again. Or atleast something stronger then just a
fantasy.
