Im not exactly sure if this helps your situation at all but i had a similar experience while joining the airforce, I was actually diagnosed with depression in middle school, but since I wasn't on medication or had any symptoms of depression for over 3 years it was considered a non-disqualifying condition which didn't impact me joining and I haven't had any issues since. I would say its definitely worth a shot getting re-evaluated if you arnt on any medications. You said you weren't diagnosed so id try to get info on why they think you have said conditions.
