I Am Recovering From Bronchitis. I Finished My Antibiotic And

I am recovering from bronchitis. I finished my antibiotic and the wheezing is gone but I still cough and I have no energy. I am wondering how long it will be until I feel back to normal? I am usually quite active. I walk 30 to 40 mins a day and do zumba twice a week. Now I am exausghed after a half hour raking the lawn. Its been three week already.
