choking

I bit off far, far, far too much to chew again.
People are expecting things from me that I'm too exhausted to supply and I'm expecting things out of me that I'm getting pissed about... I can't articulate it well, but you know how you feel all used up when you're constantly running ragged for other things and you can't seem to make heads or tails of anything and everything that you wanted for yourself is falling by the wayside? In Spanish they use the term agotada... it's like dried up. Literally dripped out or used up. That's how I feel right now.
I feel like I'm letting everyone down including myself.

I've allowed deadlines to fly by me.
I can't seem to articulate how I really feel or what I really want to anyone.
It's like the worst sort of trapped... when your mind won't stop running and it's editorializing on your whole day, judging without any sort of insight.
I feel dejected and I just want a few days where I don't have to answer to anyone or feel anything.
