Ever had one?

Ever had one of those days where it's just hard to be you?  I seem to be slumping right in the middle of one of those today.  It seems like everything I attempt to do turns out wrong, and every choice I make turns out to be the wrong one.  I miss things the way they used to be in my life, and miss people who used to be in my life who no longer are.  Sometimes I don't seem very capable of moving past mistakes I've made in the past....sometimes it seems like no matter how hard I try to put those mistakes in the past and keep them in the past, they have a way of rearing their heads back up--and the sadness has a way of creeping back in.  It's days like this that I have to really, really remind myself of the things in my last post!
