In the context of your latest update OP, I will say yes, that is DV.
My initial answer would have been a "not necessarily".
If only because I am one of those "pathetic and cringeworthy" people reference upthread. I rarely actually hit any furniture, and would never and have never hit anyone.
For me, it is a safer alternative to self harming. I am more likely to overthink punching a wall, and not actually do it, than the alternative.
And yes, that is due to trouble controlling emotions - again, referenced as childish somewhere upthread I believe.
Difference is, I am medicated, having counselling, actively working on it, and it is becoming more infrequent, only actually happening in moments of pure frustration and dizzying emotions.
Never to control or intimidate anyone other than myself. A bruise to myself doesn't leave a permanent mark or reminder.
