Can't believe my own feelings after having my daughter.

My daughter is one year old. My mom had come to take care of me and ended up staying with me for 8 + months because of covid. I lost my dad in 2018 unexpectedly due to cardiac arrest. Both my parents families are quite toxic which I clearly dint understand much as a child.

I always thought my mom to be my support system but during this trip she really misbehaved. (Snatched my baby away, said my dad would be ashamed of me for correcting her to respect my boundaries, watched me breastfeeding my daughter which I found SUPER awkward, told me to get lost on behalf of my daughter, told my daughter that her parents don't know or understand her that only her she ( her grandma knows it all), repeatedly called my daughter HER daughter. The wierd thing is when I confronted her about how she was acting, she said she was "just kidding". I know for the fact that people only say what they think so she was clearly acting super toxic. I initially tried to give her benefit of doubt since my dad is no more and that she is probably still grieving. But honestly, does grieving give anyone the authority to misbehave with others?? Now that I am a mother, I just lost all the respect for her this time and honestly don't feel like talking much to her. It's been 6 months since she left and I just couldn't be more relieved that I don't have to deal with her toxicity anymore. Infact now I even reflect on my childhood days and realize she was verbally abusive to me ( she never hit me but constantly called me the drama queen, dramatist, compared me to my aunt who she always hated). I just can't imagine saying such things to my own daughter. I feel so ashamed that she is my mom and clearly super toxic and obnoxious. I just can't believe I am saying all this about her! Am I being too harsh here?
