I've not been diagnosed but can relate heavily with the mentioned characteristics, especially the conflict between always wanting to be outside society, and the loneliness and insecurity that can bring. I have a marker in the sand between "wants to be a total recluse" and "wants to be in society and have all the normal things - but very much near the fringes". I move between them, now and then. Weirdly, the only thing that matches the loneliness of being disconnected is the anxiety of being connected....and there's the paradox. It's hard to serve two masters.
I've no expertise so....good luck. It can work with a lot of understanding I think and the right people.
