I guess sometimes grief isn't always for what we have lost. Sometimes it is for what we should have had but didn't and Mother's day can bring a lot of pain to those who either grew up with out a mother as well as those whose mother is not what one could call a mother at all.
Terri,
I don't think you were being unfluffy at all. You have every right to express your feelings and every right to not want your mother in your life if she is going to treat you badly. Nobody deserves the pain of having a mother like that. Sometimes, the best thing is to distance yourself as much as possible from the people who hurt you instead of trying to stay in contact because they are family. Being a part of somebody's family is not a 'right' just because of biological relation. Family is also a privilege and an honor. It sounds like your mom is abusing the privilege and honor of being part of your family. I hope you can distance yourself from her mistreatment and surround yourself with real family - those you choose and who choose you - those who love you and cherish the honor of being called family. Remember, family doesn't always mean biological relatives, but sometimes it's those you choose to adopt as family.
