I Need Advice

I can't seem to move on and accept the fact that my mother has no interest in being a mother or isn't interested in our lives. She walked out on us 10 years ago and it affected us a lot, my dad was heartbroken and me especially as a young girl, I didn't have a female role model for me to look up to. I see people with their mothers and I get envious a lot. I never had a loving mother and when I visited my mother, she stood me up for dinner and didn't feel bad about it. Help me.

My friends and family keep telling me to move on and stop being stuck in the past. My best friend said I have a lot of mother figures and my aunts helped me so why who about my mother not being around when she doesn't want me.
It isn't the same as having a mother.
