Sick and Tired Of Being Sick And Tired

For the last 3 months off and on I have been sick with Bronchitis. This week its taking a turn for the worst as the last 2 mornings I have woken with a burning sensation in my chest. I cant breath properly and when I over exert myself I start coughing uncontrollably. When I talk I sometimes start coughing and it hurts like nothing I have ever felt before. At night I cannot sleep properly for tossing and turning as well as coughing fits that wake me up. I went to the hospital now 3 weeks ago and they wouldn't treat me for it saying it was allergies but no allergies I have ever had had this effect on me. I am getting tired very easily these days and my body tries to shut down on me. I had a Urinary tract infection on top of and they gave me medication for that but it didnt work. I took cranberry juice and the infection went away. I am not the only one sick either my 2 children that are with me 24/7 are sick as well with coughing fits that last up to 15 minutes at a time if they over exert themselves.
