First, welcome to the forums! I've certainly broken things before, or at least potentially damaged them. I once threw an xbox controller at my laptop when my desktop's motherboard stopped working one day. Then I started screaming and crying. I don't know if this is my BPD acting up or my bipolar but whatever the cause it's certainly not fun. I know what you mean by this sort of "feeling washing over" you, only to snap out of it and realize the consequences. It's such an intense adrenaline rush.
