Looked at your profile (am anneurysm2, by the way), and so far, so good.
You are very down to earth, and honest without being too-honest. The only thing I'd suggest would be the section on "I spend a lot of time thinking about"...maybe get specific and name the most interesting thing you think about. "Quite a lot of things" is kind of vague, and with this question, people seem to get a really good sense of your personality and where you come from. I'm sure you can think of something interesting for that question.
At any rate, just keep trying...your profile looks good so I'm surprised you're not getting only a few messages make despite you taking initiative and messaging people yourself.

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.
