(((Judy))),
First of all, I am sorry about the loss of your friend, Frank and about your friend Loreen's heart attack. I am sure you were a wonderful friend to Frank and that you are to Loreen.
As for all this funk stuff, it sounds like you are just human. You try so hard to be positive and you do so much to keep others around you cheered up ( you do a good job of it too) , but even YOU have the right to have concern , worries, fatigue and all the things that go not only with a cancer fight , but with life in general. I'm so glad that you came here and shared it all with us. It helps to get it out , especially when you can share with people who not only understand , but people who really care for you.
Hope you get a good report from the labs and that you are feeling better soon. And.. give yourself a break. You really pushed yourself.. pamper yourself.
Lots of hugs,
Sue
