Where the fuck is the off switch?

I want to rip my hair out, curl up in a corner and cry.
Then get sucked into a black whole. And die.
Where the fuck did all this stress come from?
And why did he have to choose tonight to be an ass?
So what am I doing instead of
planning for my history discussion?
reading Hard times and making notes?
finding problems with the hellenistic philosophies?
working on my content analysis?
writing one of my history essay?
sleeping?

I am switching between doing my work, crying, procrastinating, imagining the worse, worrying and more crying.
I wish I could turn my brain off, just for a little bit. Go on autopilot and just coast.
Until all this shit is over with and I'm at university siting comfortably in my humanities class making plans to go out and get drunk.
