How can I make myself not worry that my mother does not like me?

I think I may have been in denial this whole time but my mother just does not like me at all. She is psychologically abusive towards me and outright tells me she's horrible to me for my own good. Since I was young I've tried everything to gain her respect but she is cold and distant towards me and outirght rolls her eyes at my attempts. I know it might sound silly it's all just built up and today it took one small thing to make me realise this. I was in a rush to go somewhere so I just picked up her hat to wear just for a second and she outright snapped at me to never touch my things. It was the way she said it made me feel as if I am disgusting for touching her things. Like dint touch my hat i just washed it even though ahes used it but me specially using ut will make it dirty. I felt so embarrassed as she did it infront of my younger siblings. How can I come into terms with the fact that she does not like me and separate myself from her and not care what she thinks.
