Was this abuse?

So when i was 15 i had a vaginal infection for 3 years,my discharge would always make my underwear brown and dirty for 3 years straight everyday. I told my mom during the years and she would say it was because i was so dirty,so i started washing my private part 4 times a day but brown would still come out after some hours,soon she started saying it was because i didn't stick my finger in my vagina to wash it proparly,that vaginas couldn't wash themselves and you needed to stick a finger inside(even if i told her it wasnt true with proof she didn't believe).

(and no she wouldnt bring me to a doctor even if heath care was free)

So one day she had enough and insisted to show me how to wash myself properly after shamming me all these years,she told me to bend down and made me stick my finger inside myself to wash my vagina,she was angry that i was finding it difficult to insert the finger(had no lube and couldn't start getting myself wet in front of my MOM!🙄) so she went and stuck her finger in me to "clean me". I cried and she got angry and hit me. That was the last time she stuck her finger in me but there were other episodes where she tried to again but she would say "well im not gonna do it since i know your won't let me" because i kept pushing her away.

You might wonder why did my mom consider me to be sooo dirty?During puberty she started showering me less so i was bathing myself,i got stretch marks (i formed very early and fast)and my hyperpigmentation got a little more noticeable(always had it)and she's so confident all this is because she stopped showering me. I never got the courage to really stand up to my mom because although she learned to control her anger issues ill never forget growing up and watching what she would do when she got angry. Might also have used emoji's to not make is seem that bad because i know my mom did lots of bad things but she was also a widow and a single mom so i dont really know if im allowed to blame her.

Edit:I think i should also add that at the end of the day i always showered!But hated the idea of showering growing up because my mom would bodyshame me soooo bad! Like i would end up crying but had to hide it becasue once she caught me and hit be badly.
