Where am I

My mind is like a wet sponge. I have all this stuff inside and the sponge won't let anything out. I'm going to get something posted even if it is mindless. I have the big head syndrome. How can I have such a big head that is so full of emptiness?

See what I mean? I either have a big empty head, or a head with a sponge in it that soaks up all the ideas I have and is to stingy to let them out.
