Two of my kids are on the spectrum, didn't get a diagnosis until they were a teenagers. Suddenly, so many things made sense. Over time, and reflection on my own life, I'm pretty sure I'm on that spectrum, too. And a bunch of other things make sense.
I haven't, and likely won't, get a clinical diagnosis. The testing is relatively involved, and regardless of what it would reveal, I don't think there's anything that would change for me in my mid-50s. Maybe you're younger enough that it would be more useful for you.
There are some parts where I don't feel like I match at all. I would say I'm better than most people at reading people's emotions. I am good with social cues and nonverbal communication. I just over think everything afterwards.
Couple of things here. One, "not being able to read other's emotions" is a regulary cited characteristic of ASD, but it's not universal. One of my sons, for example, has incredibly high "emotional intelligence." Usually. Two - and I don't mean this in a snarky or dismissive way - you might believe you're good at reading emotions, while not being as good at it as you think. I don't know you, so that could be way off base, but it's definitely something worth having a think about.
What I have come to learn is that it's okay to be who I am, whether I have an ASD diagnosis or not. It's useful for me to recognize my own characteristics and compare them to common ASD characteristics sometimes, but the more time passes, the less I need to do that.
I am who I am, and that's all that I am, I'm Popeye the Sailor Man.
