At 60 years old is it still normal to hate my mother?

I am a 60 year old female who loathes her mother. My mother is 85. I have a hatred for her that goes back to early childhood. I hate everything about her and have always tried to live my adult life so that I do not remind myself of her. She is the rudest person I know. Nothing is ever good enough for her. I could get her the best gift for mother's day or her birthday and she will respond by saying" It is nice but..." and then say what she doesn't like about it. There is no pleasing her. She is so unintelligent and sound so stupid but thinks no one else knows as much as her. My father is also still living and is 88. She talks to him like he is a dog. I have no idea why he has stayed with her all these years. He must be a saint. He is a wonderful man and I love him dearly. He is the only reason I force myself to be around her about 5 times a year. She only lives about 20 miles away from me but I never go there except for family get togethers. I remember when I was around 10 she got mad at me about something and actually was choking me. My brother had to pry her off of me. I think she would have killed me. When I was 11 she got mad and threw a wooden spoon down on the table in front of me. It bounced up and hit my face causing a laceration requiring several stitches. That was probably an accident but when she seen that it cut me and I was bleeding bad she said "GOOD". I can have a new hair do and she will say stupid hurtful things like "Your hair looks nice but that style makes your nose look big" or I could have on a new outfit and her words would be "Nice outfit but those pants make your butt look big" I hate the bitch so bad and I know that when she dies I will be happy and feel free of this hatred trap she has me in. Am I too old to feel this way or is this normal?
