The Survivors Network of those Abused by Priests, known widely by the acronym SNAP, is beginning a new confidential self-help group in the Boston area for survivors of sexual abuse. Sessions are scheduled to start Sunday and then convene every fourth Sunday of the month thereafter. This Sunday’s meeting will be from 3 to 5 p.m. at Newton-Wellesley Hospital, 2014 Washington St., Newton, near the Woodland stop on the MBTA’s Green Line (D train). SNAP’s groups are open to any sexual abuse victim who has been abused by an authority figure. Survivors and their supporters are welcome. Contact Dave O’Regan for details at email@example.com or call 434-446-6769.
