Is it possible to forgive an abusive mother ?

My Mother was extremely cold & emtionally unavailable throughout my childhood, there was also plenty of physical abuse ( this was back in the 60's/70's ) she would have happily thrown me out at 17 if it wasn't for my father stopping her.
I eventually left home at 22 & now have a family of my own plus a wonderful supporting husband ; my upbringing led to extreme anxiety:
I'm now 53, & whilst this was many years ago I still feel sad that I didn't have a loving Mother. Is it ever possible to completely move on & forgive & forget? ( I know that isn't possible in extreme cases )
Thank you.
