Well, I've been given some excellent advice on using my 02 according to my script. Thank you to those of you that commented. Trying to figure out many issues here at the home front. My husband is also end stage renal disease, doing dialysis. Trying to line up appointments, and rides has been challenging but doable. But I am finding I'm no longer as mentally prepared for things as I was say 6 mo's ago. Could be stress, could be the disease....could be I'm just worn down. Family right now is unable to help out. Any ideas on how to keep things moving forward, and still keep most of our independence ?
