Re: I didn't call my mother or buy her gifts. Am I alone?

I would suggest trying to see your mother as the flawed human she is, see her apart from the fact that she's your *mom*.
I'm sure that she's disappointed you, maybe worse. Realize that there is a lot more to her than your perception of her and give her some love.

A quote, from a DEAR friend of mine(I love this):

"I am as sane a reaction as I can be to my f!cked-up circumstances."
