Caregiving can be such an overwhelming job. I did the 'tip of the iceberg' for my in-laws compared to others on this site. What do you wish your friends/family would ask you or say to you in support? What could they do that would be helpful for you?
I ask because a good friend is on this journey with her parents (Dad with ALZ) who live with her. How can I support her in a meaningful way?
Visit. Take cake, or nice cheese, or anyway special real food rather than booze or chocolates.
If circumstances allow - her father's not too ill, her mother's not too overwhelmed, you're able to do it without never, ever wanting to go near them again - offer to hold the fort if she needs to go out.
Avoid making too many "helpful suggestions"! Ask "would you like me to find out about x y z?" rather than leaping in with "there's this wonderful new gizmo/medication/facility I've heard all about - "
Just be there.
That you've already thought to ask about this incredibly important point makes me sure you are going to be a Grade A friend to your friend. Bless you and your kind.
Prepare casserole type food that can be used for multiple meals. Do nice fresh fruit salads.
Give your time on a consistent basis so she can go do something frivolous for herself.
Help her with her housework, get a group of ladies together, do a potluck lunch and deep clean her house for her a couple times a year.
Listen without judgment to her vent.
You are awesome for wanting to be a friend for someone facing a challenging time that usually leaves people standing alone. Hugs to you.
