Was I abused?

Im new to this subreddit and I experienced this a while ago but it's still a thing that's frequently on my mind. Whenever I hear of abuse it usually involves a family member or romantic partner beating someone up but since neither of those things have happened to me I question if this still counts considering it really bothers me but I sometimes feel as though I'm somewhat overreacting.

(TW description of abuse) Im 16 now but when I was 10-11 a friend of mine (same age + gender) struggled with mental illness and would often take it out on me. This involved digging their nails into my skin, hitting me in the stomach, putting me in a headlock, yelling at me, insults. They would grow out and sharpen their nails so it would hurt more but I never bled or had any bruises to my memory. I don't remember what exactly they would say to me other than one time when they said they'd never stop hurting me. This continued for almost a year and there was a lot of other stuff going on but that's basically a summary of it all. After that I struggled with anxiety and self esteem issues. Does this count as abuse? Do I feel this way cause of trauma?
