Avoiding pneumonia after Bronchiectasis diagnosis

I was diagnosed with Bronchiectasis in February of 2018 after a third hospital stay with pneumonia. I have read all that i can find. Knowledge is power, right? However, it seems that each case is different. i find it difficult to not be somewhat of a germaphob and paranoid about trying to stay out of the hospital with pneumonia. How does everyone else handle this? do you ever want to wear a mask everywhere you go? I am on a rotation of primarily 3 different antibiotics each month for about 10 days each month. I also use an acapella, incentive spirometer, and postural drainage. I use NAC and Mucinex as well as a nebulizer twice daily. I look forward to hearing from others and how this is handled by others.
