Why do some famous people commit suicide?

Isn't being famous requiring a lot of energy?  Aren't you scrutinized, have no privacy, little private life.

You don't show up for a few days, everyone's talking?

A LOT of gossip, not good, either, in those circles.

For some reason, I've noticed that many if not most very creative and talented people also suffer from clinical depression or are psychologically fragile.  Perhaps if the creative side of the brain does very well, it costs in other ways.  All this is theory, but it is a trend I've noticed.

Psalm 37:35-37 

I have seen the wicked in great power, and spreading himself like a green bay tree. [36] Yet he passed away, and, he was gone: I looked for him, but he could not be found. [37] Mark the perfect man, and behold the upright: for the end of that man is peace.

perhaps the stress of it all, fear and anxiety maybe.

I have been suicidal numerous times. I have persistent clinical depression which is managed by medication and therapy. I grew up in a happy, loving, 2 parent home, wasn’t bullied in school, volunteer, able to do whatever extra curriculars I wanted, work, have great friends and extended family, have a university degree and a loving husband. I have absolutely no reason to be depressed; my life has been pretty good. However depression is an illness. When I become suicidal, my brain is telling me that my family would be better off without me, that I don’t deserve to be alive and that I am the worst person in the world. 

Having money, fame or things doesn’t make you immune to depression. Being a celebrity can be incredibly isolating which is a trigger. With the stigma attached to mental health, they could lose everything they have worked for if they seek help or face ridicule. I have been told so many times by people that I have nothing to be depressed about (which I agree is true), but it doesn’t make it go away. It makes me feel worse and less likely to seek help. 

Suicide is often done to avoid having one's pride hurt.

My evidence for this is having worked for three years as a crisis counselor and hearing a number of different people wanting to kill themselves.
