Could Donald Trump actually have a mental illness, or Is he just a narcissistic jerk?

Does ANY civilized country have a leader which issues statements thanking himself/herself ? 

...quite literally every civilized country has leaders which do that, albeit in more subtle terms. President Obama credited his own administration for the rising stock market during the latest state of the union, President Bush credited his administration for the booming economy before the housing crisis, etc. It's not as blunt as "Thanks, me," but the sentiment is the same.

Regardless, the possibilities for US president have been terrifying for a long time now.
