This is probably a litle late, considering that this thread was first made in October, but I do have some information for anyone in Rhode Island needing a group. There is one group that I know of, which my doctor actually recommended for me, and she says she actually does some work with them. It's called Lifelines Rhode Island, and meets in Providence every other tuesday. Their website is
here. I personally haven't been there yet, but it was recommended to me, and seems like a good place. I might be checking them out soon. Hopefully that helps anyone who needs it.
