I am very difficult to upset. So if I do ever react, or snap at, or back at you, or show any sort of negative emotion, it's not you. It just means I have a whole lot of other sh*t I'm dealing with, and bottling up that's making me very on edge, and I'm just not telling anybody about them. To my knowledge, this doesn't happen often, but in those times when I'm so beaten down that I rather not further torture myself with faking my happiness, if you want to just be around for my "good" times, but push me down for my times of weakness, please stop pretending to be my friend, and just leave me alone.
