I still want to join the military, but how can I come clean about having previously been deceptive about my asthma while trying to join?

I wanted to enlist in the marine Corp and I went to the recruiter I told him I was diagnosed with asthma but that it had been a year since I used my inhaler.

He me told to just go on with the process but to never mention asthma.

At MEPS I marked everything “No” but glasses once it came to the interview I said something that gave away the asthma but I said I only got tested for it but never had it and they asked for medical records once I stepped out the office I called my recruiter and told him what happened all he said was “honestly dude your just done” and hanged up nothing else since then. Either way I went to get my medical record and I was diagnosed with asthma but with out taking a test and in 2017 I took the test and came out negative. I did not want to take back the medical records because I did not want to get in trouble for lying because 1. I suppose I did have asthma and 2. I did use an inhaler and since my recruiter said “all the liaisons are gonna do it’s disqualify you for anything” then the “5 years in prison or $10’000fine”

I got scared and decided to just do nothing but I really wanted enlist and I was wondering if there was away to come clean.
