On most days I don't think about the fact that I don't have a mom, although I do think about my mom on most days. The reality of not having a mom has become part of my reality, but once in a while I get really jealous and I want a mom more than anything.
My friends who have moms are so lucky, in most cases. Sure there are moms that are nothin' but trouble, but for the most part having a mom is a really great thing. Especially having one near by. I can't imagine how different my life would have been if my mom was still alive. I think of all the things we would have enjoyed together, how we would have shared our lives and had so much fun together. How we would have been this link, her, me and then my daughter. A green eyed trio.
I am worst friend to gripe to about your mom. As much as I try I can not muster any sympathy for the tribulations of that relationship, and all I want to do is scream childishly "At least you have a mom!"
So, for the love of God, spend time with your mom. Enjoy her quirks, and enjoy having a parent. If you don't want her anymore................
