There is a theory that most daughters either end up doing things exactly like their mothers did or they do just the opposite. Lucky for your kids, you chose to do the opposite and love them uncondtionally. You gave them a chance to grow up knowing what love is all about.
I grew up similarly to the way you did....none of my sisters or me could do anything right in my mother's eyes. She was a very narcissitic woman. Thankfully, we all grew up having learned lessons from that, and all decided to take the opposite path. She was, however, a very doting grandmother who thought that none of her grandchildren could do no wrong. I'm not sure who she ever gave credit to that those grandchildren turned out so well.
I'm sorry that you're hurting so badly right now. I hope that you can take comfort in the fact that no matter how badly she treated you, you managed to break that pattern within your own family.
