Is there a worldwide non-profit HSP organisation or network?
Most groups of interest have some non-profit or NGO (non-government organisation) for gathering and representing their interests. Does something like this exist in any country, or even better world wide?
Like a place where everyone can go, call, connect, ask, collaborate?
There is https://www.hochsensibilitaet-netzwerk.com/ in Germany, which is mostly for Germany, Austria and Switzerland (German-speaking countries).
