You ever get stuff done and not know how?

There was something I had to do today which required me to get up at the butt ass crack of dawn and I doubted myself, dreaded it for 2 weeks and I was up last night with a major migraine and puking my guts up but somehow this morning I rose my ass out of bed and went and did the shit I needed to do.

I dont know how I'm doing everyday, I don't know how I get up for work on time. I actually do more at work than I even need to. I am so tired. Like of course I remember doing it but idk how I managed to pull the strength out of me for all of it. I feel like there is none.

I don't even know how I'm doing it.

You ever feel like that? I don't know how I'm not curled up into the fetal position in my closet floor having a break down.
