Lack of writing

What can I say? I'm very dissapointed with myself. I have not written much in a while, when was the last time I did a 'Novel Update'? A long time ago. I write a few words last night towards a short story and those poems I wrote last week were kind of...blank. I'm not in the same frame of mind I was last year, when my english teacher inspired me to take up writing again. The ideas are there, but for some reason I can't let them out. I've got a puzzle with lots of the good pieces, but I lack the little bits that make it whole. All the little technical bits, like starting off a conversation or moving from one critical scene to another are all missing and it's shitting me.
