unsure what to title this

ever since i was around 6 years old, my mum has been touching me frequently. she touches my private parts regularly and always makes weird comments about my body. its been 7+ years since it started, and it still happens and i dont know what to do. i cant tell her to stop because she'll say "im ur mum i can do what i want" or whatever, i cant tell my other family members because they all have the same mindset as my mum and im not enrolled in schools due to family problems so i cant tell anybody else. i dont know if it counts as sexual assault or not, because i feel like its really not that serious, i never got actually raped but she just touches me in spots where she most definitely shouldnt be i feel disgusting all the time, my own body is repulsive to me and i can constantly feel her hands on me even if shes not there. my dad makes weird comments about my body too. am i overreacting? what should i do to try and feel better about all of this?
