Asthma and a patient's personality and emotions are very intrinsically bound up with each other.
I am thinking perhaps changing how you feel about
the old you and the new you are
Use Positive Language. Think Positive Thoughts.
Try not to use negative words too much like hate, disgusting, sick, etc." Notice how things have improved in the world, in your town, in your life. Look for beauty. Try not to be sarcastic. Sarcasm is a "put-down"of something or someone. The way you act in the world is basically a habit. You can retrain your behavior and your thinking, and you will benefit by doing so. Being considerate, kind, and positive is contagious and worth the investment.
You are a strong person and you will overcome your fears and learn how to compensate for your ASthma.
