At times, everyone gets upset or annoyed and doesn't feel like talking to anyone. But lately, that is me all the time and I can't hide it or stop it from consuming me, even at work. I get extremely agitated with customers because I don't want to be there talking to them. The most I can muster is a "fine" with a straight face even though I'm not fine. 

When I'm upset I want to be alone because I know how I get. I can't pretend to be okay even though I can see myself from the outside causing destruction. If I keep this up I won't have a job anymore.

The worst part is the reason I'm upset all the time: a guy I like won't talk to me as much as I want. We've had a few conversations but he consumes my thoughts and it's making my life miserable.
