As others have suggested, for most of us that are older adults, the diagnosis (often of the ASD-1/Asperger's/so-called "high-functioning" variants) is primarily for you, and you alone. Sometimes it helps to look back at your life and put things into proper perspective. You weren't a "failed neurotypical", but rather someone with a previously undiagnosed autism condition. For many of us, it is a relief, a weight of guilt and misunderstanding lifted off of us.
Now, the next step is taking that "deep dive" into "all things autism" in order to learn about all the aspects, genetically, physiologically, anatomically, immunologically, psychologically, etc., etc. If nothing else, you educate yourself, but beyond that, you have a better understanding of yourself, you become more self-aware, you have a different perspective and context regarding yourself and others, etc. You should allow yourself some "grace", some "humility", and when appropriate, you can have a sense of humor about yourself and laugh at yourself sometimes. Just because you have a "condition", it doesn't mean that jokes are off limits. You can roll your eyes at yourself, call yourself out on your own BS, shake your head in disbelief, and have some fun with it. It's all about your attitude and how you deal with your daily life. With this new knowledge, there ARE things you can change about yourself, but do recognize that there ARE things we cannot change, so don't allow yourself to become distressed about it. "You can't run certain software if you don't have the hardware." Adapt and overcome. Find a different way to accomplish the same things in life and in your professional career.
