When my mother went to the hospital for a large surgery (can't remember which one, she had several) there was a woman in the bed next to her who loaned her a teddy bear. "It helps to hug it tight if you have to cough," she said, and it really did. When Mom got out of the hospital she bought herself a good teddy bear about that same size and named it Betty, after the wonderful woman who loaned her the first bear. And in her will, she left that bear to my sister's best friend's cat, because the cat used to always curl up with that bear when my mom was cat-sitting.
Anyway, a bear like that for purely medical reasons, but also for comfort, would be a good idea. Maybe someone who loves you can give you the bear, and make it all the more significant for you. Do you have a checklist going? Add a bear to it, bonus points for a bear from a loved one, but you need to love yourself right now, so it's okay if you buy it.
Michelle, if you'd gotten through when you called (you still can) I was going to make the point that you need to take that incredible energy and drive that you have employed for a couple of years now in working toward the adoption process and apply it to yourself. You are adopting yourself right now, and all of that nurturing needs to be directed inward. You do need to relax (in your mind, not just with drugs--really--this is imporant!), and understand that the procedure they are proposing is the best approach. Abdominal surgery lets them see best and get everything they need to remove. It's the option I had to let my doctor have, so if he felt they needed more access during the surgery he had my permission. (Think about having them take the ovaries while they're at it, if they give you a choice--one less thing to go wrong later, IMHO).
Losing your uterus and ovaries is losing one of those "chakras" (sp?) you may focus on in yoga or various Eastern religions. There is something to be said for coming to peace with this process, and that did (for me, anyway) mean mourning the loss of a part of my life, that of having children. The cancer is a reaction to something going on in you, but by removing the cancer you do lose something, and it'll take time to think it through. You'll come out stronger in the end, and you'll look at your friends and loved ones differently, and realize what a gift every day is. I don't have a religion, and I don't believe in a god, but I can see this very clearly without the formality of religion.
For now, relax, pamper yourself, and call if you want to.
