I am sorry to hear your grandmother passed away. My hubby and I took mine in when no one had enough time to devote to her as she had alzheimers. She passed away at beginning of November and I had just gotten out of surgery. I just, ugghhh, too much at once it seemed.
I hope you take some time for yourself and allow the memories of good thoughts on her flow with your tears...maybe in a shower (so when you all slobbery and snotty it is easy to wipe off :P )That seemed to help.
I hope your tests are going to come back letting you know some definatively things going on and that youe whole health is returned soon.
