Confusion

All of this paperwork is confusing me. I just got something from Atena re: my living will and the Power of Attorney. They are saying that the person with POA can't be in my living will. That, to me, is insane. My Fiancee is the one who is responsible for my POA if my sister isn't avail. But guess what, the POA can't be a blood relative either. 

I don't know what to do. There are a total of 2 people who I literally would trust with my life and my belongings and they can't be my POA and/or be on my Living Will. 

What am I supposed to do?
