Extremely sore throat. It was my anxiet!

Hello, I am fourteen years old, and on March 10th my mother had to take me into emerge as my throat was sore and I would be coughing non-stop to the point where I would be unable to breathe or I would start gagging, I would also wake up in the middle of the night or morning unable to breathe, the first doctor said it was croupe, have me a inhaler chamber as I already have an inhaler due to asthma and the doctor also have me a shot of steroids (liquid form) and said it should be better within 3 days and if not, then to see my family doctor. I then seen my family doctor as it didn't stop and he then told me that it was influenza and there is no medication he could give me. On April 13th, my mother had to take me into emerge again because the coughing and everything else died down but didn't actually stop and I woke up one morning and realized my throat was sore and it was slightly hard to swallow but I just thought it was nothing as it happens occasionally and I thought it was my anxiet
