How do you let go?

I have received the call that all children dread. My mom is in the hospital (ICU) and she isn't expected to live for much longer. The last few days have been really tough. I mean, how do you let go of the person who has inspired you to be everything and more? I know it's time and she's always made it quite clear that she doesn't want live this way and I can't say that I blame her. It's just a lot tougher to actually "say" it than I ever thought it would be.

I met with the hospice nurse today and she did help alleviate a lot of my concerns, but I can't help hoping that she will pull through this and get better. I love you mom!
