It turns out that Karen and Don live only 30 some miles from Jack and me. I have talked to her on the phone several times and she has my numbers if she needs someone to talk to. It turns out that Don and Jack were in rooms across from each other after their surgery. What a coincidence. I didn't meet them. Jack kept chewing me out for bothering people so I tried just staying in his room.
I hope I can be some help if she needs someone to talk to that is experiencing similar things.
