Days where I have this fist squeezing in my chest, right over my stomach. It feels like I can't breathe very well, and all I want to do is curl up into a tiny ball and cry, and be cradled. I don't often have the luxury of the first, and I never have the opportunity for the second.
That second one is generally what brings it on, too. Just... Crippling loneliness. Not the kind which can be solved with friends, either.
I'm never entirely sure what is going to bring it on. What one day will roll off my back would just stab me right in the gut another.
But what can you do, right? Just kind of soldier on, I suppose. It gets old, and exhausting, fast though.
