Thanks so much for your thoughtful response, Katherine. It means a lot to me. I have been a little muddled this weekend, trying to think things through. I do have a lung functioning test coming up, and a follow up with my infectious disease specialist, so he may have a different opinion than the respiratory specialist. I will see what transpires from that. but in the meantime, am focusing on trying to stay as healthy as possible. I appreciate being part of this site and the connections made. I feel very supported.
