Hard to know what goes on behind closed doors.   

IMO the President is intellectually and emotionally unfit for public office.    

I can see that he has had success in his personal live and I'm assuming he had enough skills, (or purchased advice), to manage his life to financial success.   It may be his age that is causing the problem?   He can't take pressure anymore, he has to seclude himself in his private residents.   He has trouble form full sentences or completing a thought, (ADHD?).   He's clearly defensive to the point of paranoia, boarding on the classic description of a sociopath.  

If he was family or neighbor, I would assist in getting him mental health counseling or possibly a higher level of psychiatry, but I'm not sure how deep his psychosis runs?   

For the sake if President Trump and his family as well as our national welfare, the man should be examined by professionals.  

Do we have a President in a mental health crisis?
