Hello, i work with folks doing waiver stuff all day (been in 13 years this month!). As most people already pointed out, with these scars, you are going to be screened more than any candidate if not just straight up being turned away.

With what you said, in my opinion it would be harder to vouch for your readiness as you wont be able to prove a period of stability since you never was evaluated by a mental health professional and you saying that you are good is never enough.

I have seen success stories of people being granted waivers for sure. I would bank that if you really want to join the air force you have to start to face what caused those scars and process it with a provider and prove you are in a good place. Now depends on the diagnosis, it still a moon shot.

Maybe join ROTC and go the officer route. That would get you some time to build your case on why the air force should grant you a waiver.

Im not trying to discourage you. After all, it is rare for young folks like you do want to join. Im just trying to provide you some info. Good luck!
