I've managed adequately for 63 years and retired from the USAF after over 25 years.
I'm self-diagnosed for autism, ADHD and Alexithymia. My issues are mild but have caused quite the stirs, over the years. The self-enforced isolation bothered me, in the sense I am not like my peers and don't understand them. I have most of the honesty/loyalty/no nonsense attitudes of the community and that caused conflict.
However through necessity I learned to take care of myself and create potent defenses against Allistic attacks.
My main point here is that I experience many of the same difficulties, just not to the same degree as level 1 - 3. Does that mean I am NOT autistic/ADHD?
The short answer:
That has nothing to do with it.
There are "alpha" and "beta" personalities. An alpha will have some combination of these traits: One who is a quiet observer, doesn't take any crap from anyone, is there to help and assist, is the teacher and mentor, doesn't exhibit controlling behaviors, can lead from from the front or from behind, doesn't need the attention, is responsible to a fault, is comfortable with who they are and doesn't have to project, is rarely intimidated, etc. Of the "sheep, wolf, and sheepdog" analogy, the alpha is the "sheepdog". The beta is the opposite, and will exhibit some combination of these traits: The first to open their mouth, is the perpetual victim, no matter the topic, it's all about them, would rather withhold knowledge, will want to control, sometimes with intimidation, will easily be intimidated, will have to remind others that they are the leader, will draw attention to themselves, they project a false personality, and nothing is their fault. They can be either the "wolf or the sheep", the "predator or the prey". So, depending upon where they are on that spectrum will often lead to all sorts of associated psychological and personality issues.
I am going to guess from your post, especially being retired military, that you're probably an alpha. Adapt and overcome, responsible, strong sense of "rules of conduct" and moral compass, the "sheepdog", etc. You have your issues, but you are one to just internalize and deal with it as best you can. You take on challenges head on. You have a competitive streak. You see opportunities, not problems. You learn and apply.
An autistic can certainly be an alpha, but many are not. I tend to bring up my autistic traits and experiences as means of conveying that another person is not alone. Then two, how I approached it and made attempts to adapt and overcome. I am far less likely to bring up a difficulty I am having and seek answers and attention for myself. I have all the communication, sensory, and social issues and deficits that someone else here might have, or at least I have learned ways to minimize the effects. What I have done works well for me, I will share, and if it helps someone else, great. However, I quickly loose patience with the "perpetual victim", where no matter what I or anyone else has to say, they've got every excuse why "they can't".
