At 25 I only now have fit the puzzle of my life together and found out it's most likely AS. I would say that some of the depression and anxiety I've experienced during the past 10-15 years comes partially from the exhaustion of figuring out how to navigate these social norms.
I hate saying "Hello, how are you?" because I KNOW my voice sounds weird, flat and fake when I say it, and I feel like it's so painfully obvious to the other person that I don't really care, I'm just doing what's expected as a part of polite interpersonal interaction. It's that "pretending" in professional and personal settings that forces me to spend a LOT of time alone recharging.
