awwww I'm so sorry.
I did that to my mom too.... I left her without a word and moved in with my dad. I know I broke her heart and hurt her feelings big time, but I was young and angry back then. I got over it and my mom and I have a good relationship now, and have for awhile. It seems being a parent is the most thankless, emotionally painful job you'll ever have in your life. I don't know if your pain will heal, but your daughter will grow up, mature and your relationship will get better, that will be when you heal. (((HUGS)))
