Why do people say this?

I'm hormonal to the point where I'm sure my brain is just playing tricks on me. I'm sad, annoyed, and disappointed in myself with where I am professionally and it's been digging at me more and more these days.

I'm tired. I'm sad. I don't want to be reminded I look like crap too. I'll try to remember to get up early tomorrow to put on makeup if it will make you feel better.
