OP: you're not sensitive, but you are very cautious, which is a good thing. I've learned recently that it's wise to not form any type of connection with someone you initially get a "bad vibe" from as you will end up hating them even more.

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.
