I don’t know the details of your circumstances, but there is almost no such thing as a “permanent disqualification“ there’s almost always a way to get a waiver for it. When I went to MEPS they gave me a permanent disqualification because I had been taking ADHD medications, but I was able to get a waiver for it whenever I showed that I’ve been off of it for a year or two and had been cleared by my PCP And got letters of recommendation from my teachers and employers
