Spiraling down

I destroyed a friendship today. Perhaps this person will forgive me, but my interactions with him/her will always be different from now on. I think deep down I wanted to hurt someone, and this person was the easiest target. Let's just say that I make very unwise decisions, and am very good at burning bridges. I lash out at those around me, when what I really need is just a hug. If she/he is reading this, I'm so incredibly sorry...
