Dealing with a Long-Term Cough and Possible Pneumonia

I’ve never had pneumonia or asthma before, but I’ve been out sick with a cough for weeks now. It’s been stressful having a bad cough for such a long time with Covid and all. I’m getting another X-ray tomorrow because it turns out I might have pneumonia and my doctor wants to check that I don’t have tuberculosis! :/ they also said they think I’m having an asthmatic reaction to a viral infection. I keep having coughing bouts that are stressful and uncomfortable. My head hurts. I overall feel awful. It’s hard for me to keep track of all the meds too… how do I feel comfortable physically?
