I don't approach people in situations where the situation isn't explicitly social. For example, when I'm at school, I focus on the lecture, since in the past, I've found that having to chat to someone new is distracting and anxiety provoking.
As well, I don't approach people when I think I won't have anything in common with them (i.e. I'm at an even where I don't know a single person there). However, when I can think of a mutual theme to bring up in a conversation, (i.e. my friend has hosted a party, so the girl in the corner will know my friend), I can easily strike up a conversation.

Given a “tentative” diagnosis as a child as I needed services at school for what was later correctly discovered to be a major anxiety disorder.
This misdiagnosis caused me significant stress, which lessened upon finding out the truth about myself from my current and past long-term psychiatrists - that I am a highly sensitive person but do not have an autism spectrum disorder
My diagnoses - anxiety disorder, depression and traits of obsessive-compulsive disorder (all in remission).
I’m no longer involved with the ASD world.
