What types of support groups are available for children who have parents in a SNF due to their age and inability to self-care?

Did you ask the SNF if they have a support group?

You're on one right now.

Support groups are specific to a much more generalized subject: for instance, Aging Care, Childhood Trauma, and etc.; within said support groups are subgroups of people suffering from more refined individual situations. For your subject, AgingCare Forum should be perfect. Have you a question for us?
