please sleep

am I the only one who thinks this is annoying: when someone leans on a subway pole so that no one else can hold on to it? I actually find myself laughing out loud at the absurdity that one would be so unaware of their surroundings that they don't understand how annoying and selfish that is.

Anyway, it's 4:48 and I can't sleep.

there are several things I'm worried about. In no particular order:

get a letter from a professor that I don't want to ask for.

my job. I already think they want to fire me.

my classes; I don't like any of them and worse, I don't get any of them.

I'm alone.

I exercise every day for 2 hours and I still feel fat.

I'm a size 4/6 but I want to be a 2/4. It's so frustrating.
