Wow! There are several things going around here, or it has been through this past winter, mostly things that affect your upper respiratory system and they have been making folks really sick. I haven't gone back to a mask, but I have limited what kind of crowds I have been willing to come in contact with. I'm hoping most of that will clear up as spring is coming in.
I'm so sorry you had to go through all of that. It sounds terrible! Glad you feel you are finally coming out the other side now.
