Cystic fibrosis or am I paranoid?

Hi, I am a healthy 25 year old male, who runs and plays basketball twice a week. I was diagnosed with bronchitis around April 3rd. The cough lasted for about 6 weeks and then went down to 3-4 coughs a day for a few more weeks. It’s been almost 2 months now and I am still feeling the rattling in my chest at least once a day, then it stays in my throat, this goes on around 11am-2pm. especially if I drink water. It then disappears until the next morning. For the past few weeks I only cough once or twice, which is a wet-cough. During the whole 2 months I only spit out phlegm twice, it was a greenish color. Now, Its just clear mucus, not sure if that’s because I am unable to properly spit out the phlegm. For the past month my nose also feels congested and I had to blow my nose 4-5 a day. That has now eased up.

So far I’ve taken azithronmycin which completely helped me get over the annoying coughs that lasted all day (6-14 wet coughs). Also taken IOPHEN-C for a few weeks now and Claritan. My chest X-ray at 6 weeks came out perfectly normal.

I do not feel fatigue, no chest pain, or  no difficulty in breathing. The doctor said I had swollen lymcnh nodes.

Ive done some research and I was wondering could it be these conditions:  Cystic fibrosis, antimonium tartaricum, GERD,  post nasal drip, or asthma (diagnoses with mild asthma when I was 16 after catching phenomonia).  I am worried sick right, please help

I just stumbled on 'cystic fibrosis' while looking up chest rattling/

Stop worrying!  Ask for a pft (pulmonary function test) to evaluate your "asthma".  You may have an Uri (upper respiratory infection) with sinusitis.  If it asthma then you should learn how to treat your symptoms when they occur.  You are getting into genetic diseases for being sick for a few months. You are going overboard.  Get off the computer and live!  Life is to short.  Exercise, keep your BMI below 25, eat healthfully, keep a good attitude, love, be thankful and live well!
