I am writing to say thank you to all of you for your kind replies. Mom is now in a coma, and my sister is here with me. This truly is the saddest time of my life, as I'm one of those life time singles who chose to remain home with parents, to be here to take care of them. I lost my dad seven years ago, and now mom is about to leave too. And so, at least for now, I seem lost and wondering how I'm ever going to go on. But I will - a day at a time.
Thank you again for all of your replies to my original posting, and I'll keep in touch.
