Out there

Today is huge for me.  I have sent my manuscript out to one of the publishers on my list.  It is hard for me to wrap my brain around this fact.  So many years went into this project, and 99% of the work was me, and only me, with the book.  Eventually I told people about it....let them read parts, and now it is done.  I don't know how to feel.  It is, in a way, anticlimactic.  I feel a bit numb, as if a big part of my brain has been downloaded onto a separate drive to free up space.  I fill like I need to fill up that space with something, but I am going to give myself time to figure out what should go in there.
