Question about the army?

So when I was 12 my father passed away during service, say what you want about it but he was a good guy. Army ranger. I've always wanted to join but he always told me that I have to have physical strength which I do but my recruiter said that since I have bronchitis that it can hinder my abilities in endurance. I don't feel it when I run but it acts up a little when I get a cold but it really doesn't effect me but he said at meps they can cal me out on it and Iwill not be able to join. my recruiter is legit he's really trying to help me out but at the same time I feel like he's tryna push me away because of my bronchitis. Help?
