Thank you to everyone who wrote me on the board and privately.
My mom was released from the hospital after "passing" a test that tells the doctors her treatment is working. As best as they can tell, she had a heart attack brought on by a blockage in an artery. She is being treated for the blockage and they are trying to figure out how badly her heart was damaged.
She's happy to be at home, and able to have her tea again just the way she likes it (she spent too much time in Yorkshire to like US hospital tea!) and will probably sleep better in her own bed.
Again, my thanks to you all, and when it comes to matters such as this, we really are a community.
