Having a support system is most important. Friends and family that can help when needed. Most of them don't truly understand how impactful this is to our lives, but they are usually willing to help, so I think it's important to ask for help when I need it.
In addition, Ashley Varner at Emory runs a virtual caregiver support group for those with young onset dementia that I've been to a few times, which is really helpful. It's the third Tuesday of each month at 6:30pm and you can reach out to Ashley.elizabeth.varner@emory.edu for more info.
I've also found a couple of Facebook groups that are helpful: Early-onset/Young Alzheimer's Female Spouses Caregiver Support Group and Spouses of those with Early Onset Alzheimer's Disease.
For kids, there is a great group called Lorenzo's House - https://lorenzoshouse.org/
If anyone has any other resources that have helped you, please let me know!
The Facebook for Female Spouses/partners has been a Godsend!
