Support group for parents of ED/LD teen

Our 13-year-old son has a alphabet soup of afflictions (ADHD, bipolar, OCD, ODD, Tourette syndrome and anxiety disorder). When he was little we read scores of books and attended support groups that helped us develop good techniques for working with him, all of this when we lived outside the Bay Area. The older he gets the more apparent it seems that we need new skills. Can anybody in this dialed-in network suggest either helpful literature or support groups? Many thanks. Anon
