Are there any care giver support groups I can attend?

Also, psychologytoday.com is a good resource & lists by state.

And you have found virtual support here.

Call 211

Please check everywhere you can. Call your MD office. Call any senior centers in your area. I found out there are excellent ones in Palm Springs at a Senior center. Call all the churches. Call Social Workers. Check everywhere you can conceivably think of for support.
As to "she doesn't want to go there". Life doesn't always render a choice in some matters. Sometimes you must do what YOU need to do. Not what she "wants". Unfortunately, the end of life isn't about it all being our own choice. Sometimes we have to do what works for the caregiver. While occ. our elders ACT like a two year old, they are NOT two years old, and even for two year olds, giving them whatever they want because they want it doesn't work and isn't good for them.

I would contact your local hospital. They usually have many support groups that one can choose from. I attend two support groups at times - one for diabetics Nd one for chronic kidney disease. As my brother progresses I plan to pick up one for Parkinson’s.
