I'm so sorry you're having such a rough birthday. My mom and I have never been very close, but we have started spending some time together in the last couple years, since I've grown up and put things behind me. It's my grandma that I miss so much, she and my grandpa raised me because mom didn't want to deal with my health issues, and now my sweet, wonderful grandma is in a nursing home at the age of 63 with Alzheimers. She doesn't speak, so I don't know if she recognizes me or not, but only rarely does she have that look in her eyes that I remember so much and love so much.
Just from your post, it sounds like your mom was such a special person, I'm sorry for your pain.
