Pain.

It's been brought to my attention that my facial expression as of recently could be misconstrued as angry/pissed off/rude.
It's pained. My expression is pained.
I'm doing everything in my mental ability to not burst into tears and walk out of the store and crawl into my bed.
I'm in pain.
It's not physical, really, but my whole body is rebelling and I've gotten to the point where I'm so upset that I will go dry heave in the bathroom and cry.
So if I look upset? I am.
I'll get through it. Just let me mourn, a little.
