NAMI's Peer to Peer class includes some planning tools like this as well as a mental health power of attorney form (or it did when I took the class 3 years ago). I no longer have that binder as it didn't pass my "moving to 500 sq ft only vital items go" test a couple years ago but if you can find the forms or contact your local NAMI and ask if you might be allowed to have a copy that could help. Or even take Peer-to-Peer, it's a pretty good class. I was so sick that I don't remember it overly well but it helped me even that sick.
