Oh solocarolina, I soooo hear you! And have broken and destroyed far more-- things, not people, but still... I think it is often about impulse control, which can be a big problem for BPers, but the low impulse control impacts many other issues as well. (On the rage front, it would be like a big white lightning flash that I often couldn't even see coming, so counting to 10 etc? Not even time to think of it and couldn't stop till it exhausted me.) My meds have been a big help for me in this regard, but not the way to go if there is something else going on.

Have you been diagnosed? If not, it may well be an anger management thing. Rage is not diagnostic for BP, so be sure not to assume that's what is at work here.
