Is this emotional abuse?

Hey, I'm doing well mentally so far (apart from some strong self-doubt, etc.) because I'm pretty good at dealing with crises. I'm now wondering if what I experienced was emotional abuse? My parents are divorced and I live with my mother, with whom I have a very good and close relationship. My parents only separated in 2018 and over the course of this year I've had to watch my parents physically attack each other. There was a lot of fear involved, etc. To this day, I only have a fake relationship with my father. I don't care about him at all (in my eyes he's the "bad guy"). He's very hypocritical, so that the rare occasion I see him, nothing usually happens. My mother, whom I love more than anything, who loves me more than anything, and does a lot for me, has "blackouts" every now and then because she's emotionally broken because of my father, so that she's different from who she actually is sometimes. If that's the case, then she shouts at me with things like it's my fault, that I'm useless and that I would destroy her… but in the end when this blackout is over she is very sorry and even if these phases last a long time I know that they are never meant that way, but it can still escalate very loudly and blatantly with her

I'm dealing with it quite well and wouldn't leave her (it just hurts a lot in those moments). Is that still emotional abuse? Or rather neglect?

Is this a dysfunctional family?
