A Thermos Full Of Acid.

I feel like there is one of these buried inside me. I know how I am supposed to be, and so I put a shell around this thermos and painted it to look human. Human with a sense of humor even. But this thermos is always there. Part of me is always, no matter how I actually feel, in an under current of *uck this and *uck you and *uck 'em all, go to hell, blah blah blah. The REAL problem however is that sometimes the acid get's through. I don't always know it's coming either. I could be joking in one breath and wanting to kill you with the next. I know that this is no way to be. Like I said, I hold it as best I can. But it's know picnic living with this either, let me tell you!
