A day late a buck short

Dear Mama,
After 24.5 years of knowing you, I think we've finally figured out a "schedule" that means that we can put up with each other. We only speak every two weeks or so, even though you live less than an hour away from me and Sam. We speak for between 5 and 10 minutes, updating each other on important-ish happenings: your partner has taken a 30% pay cut due to the recession; AK has been back to the vet again; the 5th of June is my graduation in Kamloops; my cousins are coming from Germany at the beginning of August. What doesn't get talked about is anything to do with my father; how my depression is faring (other than letting you know I'm back on/off meds); any mention of my grandmother's estate; any mention of my great-uncle's estate; and anything to do with your drinking, among several other hot topics.
I know that Mother's Day is supposed to be honouring the most important woman in your life, the woman who gave you life, but in my case I'm still so very, very full of anger and hurt over how the last 15 or so years have shaped up between us. It's very difficult for me to look past some of things you have said and done, about and to me. This is one of those occassions in which I feel the negatives do outweigh the positives.
I wish that we could have the sort of relationship that I hear others speak about. The one where a girl's mother is her closest friend and confidante, her greatest supporter and fan, and in turn, the daughter would do anything for her mother. I know that you and Gramma very much had this sort of relationship, later on in your lives. I hope that one day you and I can have that also. For now, though, I'm too deeply hurting. I'm not sure that I'll ever be ready to take the next step towards mending our relationship, and you have already indicated that you just won't.
However, you're still my mom, and much as our relationship is love-hate, I just want you to know that I do love you; I am just hurt and disappointed that this is what our relationship has actually turned out to be.
I'm sorry for that.

Meggie
