Chances are that at least one national group, focused on your particular concern, already exists. You may be able to join an existing group, or if no groups exist in your area, then you may be able to form a "satellite group" if you share common values and interests.  To find any existing national group, search for the terms or conditions you are seeking with the words "support group". You can also narrow your search to your local city or county. Obtain any how-to guide, or group starter kit, that the national organization offers (many provide them free online). If there's no national group, see if your search results revealed any "model group" elsewhere in the world, which you can contact and duplicate in your area. Try social groups sites and social media pages to see if local groups exist. Learning from others, even if their group addresses different needs than the group you want to start, can help you plan out everything you'll need from the ground up. That way, once you organize your group, you will have the guidance you need to get started. Social service workers, clergy, and physicians or therapists may be helpful in various ways, from providing referrals or meeting space to locating other needed resources.
