My Dr has never said what stage I was in? I hear all about them but have no idea what stage I would be in. I am disabled, but I still take care of my brother in law that has had 3 brain surgeries in 3 years. He can walk, but his speech is very limited and has no use in his right arm. So I am his cook and pharmacy. I am on oxygen 24/7, use a nebulizer, trelegy and a rescue inhaler. I have always suffered from anxiety and depression on meds for that and my seizure disorder, hbp.
