Sometimes, unfortunately because of legalities, this happens more than one would like it to happen.

Regardless of whether or not your friend is paranoid, he/she has a right to make his/her own decisions regarding their care. That is a legal right, and unless someone goes to court and proves to a judge that this individual is beyond being able to care for themselves in the basic of ways, there is nothing more that the doctor can do for them, providing they are not going to injure themselves or another.

Going to court to take away an individuals rights is a very difficult thing to do. Judges do not easily take rights away from people. Unfortunately, this friend of yours may go through some more difficulties before this doctor has a sound clue as to what their issues are. Lord knows it's hard on the family and friends......I will keep you all in my prayers and send healing thoughts.
