I moved to wa about a year ago and I've been searching for a caregiver support group. More specifically for spousal caregivers. It's been quite a disappointing search cause online the caregiver support system looks amazing but as I searched deeper, I'm learning it may all be for show. I've called a dozen agencies who have referred me to a other agencies and so on but none were able to directly give me a group I can't contact to join.
Good luck!
(And participating on the forums here, or perhaps at a site specific to your spouse's disease, can also be immensely helpful. I've done both for years. Great help!)
