Gail, Yes, you ARE a very special person. Always thinking of others. Perhaps this little idea will bring some measure of relief to you. I know you pray for others, but I don't know if you are praying for yourself. Please do, for the more pain free you become, the more you will do for others. You're just that way.
Also, as you ask for relief from the tumor and it's pain, close your eyes and imagine yourself magically taking the tumor out of your head and putting it in a pretty basket with a lid on it. Then tie that basket to the string of a BIG strong, helium Balloon. Make it whatever color you want, and tie it on real good. When you're ready, let go of the basket and watch as the balloon lifts the backet up to God. Don't take your mind's eye off the basket until you can't see it anymore. Then just say, "Thank you God", and go on about your day's work. It just might help.....
Sharing big hugs with you LCM.
