I think so. Formal diagnosis and issues with socialising can't be wrong. I often get subconscious misunderstandings in conversation which wouldn't occur if I was "on the ball". Socialising just doesn't usually come to me naturally so I have to really concentrate which itself comes with issues, possibly due to ADHD, but I've had occasional conversations which were more relaxed and on autopilot.
One of my supervisors at my old workplace suspected a bit of autism, but my online friends don't think I have it. One or two have picked up on the fact I sometimes misunderstand them but they chalked it down to social anxiety, and they're likely on point - many of my social mishaps are rooted in anxiety. It's never a big enough issue I've had to raise it with university or future employers, but people interviewing for a job involving heavy interpersonal skills would find me unsuitable.
I wonder if these relatively benign symptoms would become non-issues if I dealt with the source of my anxiety, which I'm slowly addressing. I've started attending an ADHD clinic and I hope I don't reach a dead end (if they don't diagnose me, they can hopefully get to the root of my anxiety).
