Since the end of March, I have had 3 eye surgeries and had a pacemaker put in because my heart rate dropped to around 30. I was very depressed after getting the pacemaker which I guess is pretty normal. After the pacemaker was put in in July, I got shortness of breath. Now I have been diagnosed with COPD. The doctor gave me Symbicort, but I am not tolerating it very well. I have a call in to get something else. My husband is disabled and sometimes I feel the world is crashing in on me and I am so tired....no energy. Is this a common reaction?
