Tired

I had a really long day today: I worked nine to five, after having gotten not quite enough sleep, and I've been hearing this bullshit from HR saying I can't apply out until a whole year as a full employee!!! Everyone else, including some HR people, and the policy which I've read several times, but whose link is broken, says it's only six months, with your supervisor's approval.
Of course, on this particular day I tried to step up my game, be a little more responsible, and of course people were condescending and obnoxious to me.
Then I went to class, which was a long and frequently confusing lesson on grammar. I learned some confusing terms, such as noun phrases ("Give the box to whoever asks for it", whereas I assumed it would 'whomever') Towards the end of the evening, I started to feel really spacey, like my brain was shutting down.
Then the subway stopped at Jackson, two or three stops from my place, and I had to walk a couple few miles from the skanky part of town, half asleep, in humid weather, with a dying phone and no real dinner in my stomach.
