I think that there are too few of us to have a regular support meeting like AA. However, many have formed groups who live in the same general area and meet a few times a year to visit and exchange war stories. The big group is the Annual Clusterbuster Conference. In 2020 it will be held in Chicago in September. It is truly an amazing experience to meet a big group of people who have CH!!! Well worth the money and trip. You will learn a lot and be surrounded by people who 'get it'.
ATB!
