Insert Clever, Sarcastic Title Here

I think I am an exceptionally angry person. I do my best to keep it together and put on this veneer of politeness and normality but right under the surface I am this twisted mass of bitterness and frustration and the veneer is wearing real fucking thin these days. I think I really used to be a nice person, but I don't think I am anymore. I try to be, or at least act like I am, but I am finding it harder and harder to fake. When I interact with most people I smile and make small talk but after a moment I feel this anger seeping through. I can feel it just under my skin and I try to stop it from showing on my face, but I'm never sure how well it works.
