Thanks again, all.
So, yeah...today has been pretty exhausting. We made it to the hospital and visited my wife's sister. Frankly, she looks awful. The allergic reaction to the chemo took a real toll on her. She is very swollen with severe rashes on her body, and she is completely unresponsive with minimal brain activity.
In less than one week, after a single chemo treatment, she went from alive and kicking with the hopes that the chemo would help her, to being practically dead. Apparently, she did have cardiac arrest a couple of days ago and it took them nearly fifteen minutes to get her heart going again.
The family's instructions are not to do that again. If her heart fails again, let her go. Right now, we're just waiting for a couple more family members to get here.
