Paul Morphy :( so sad to read this part

Regarded as the first unofficial World Champion. Within 2 years of playing international chess, he went cuckoo. Chess rearranged his neurons and he was no longer the same. He spent the last decade of his life wandering around the streets of New Orleans aimlessly, talking to himself all the time. He died a beggar.

This is not fake he suffered mentally and you can google about mental sickness he suffered due to chess

This might help you go through this one 

He did not die a beggar. He died with approximately $147,000 - a HUGE sum of money back in the 1800's. 

If you ever go to New Orleans, you can go to the house he lived in. It is now Brennan's restaurant. It is across the street from the New Orleans Courthouse. It is spectacular. if you go upstairs you will find the chess room. 

I visited two years ago and sat in the chess chairs with my wife. I replayed Morphy's famous game - The Opera Game - on the chessboard. It was awesome.   

Wow. Thank you for the idea if I am ever in New Orleans.

Suspicious to say the least. Sad to hear many people lose it to chess though (probably more competitive stress that does it I'm guessing). Bobby Fischer is a common example, but naturally others have suffered too.

Countless people throughout time have had mental health issues, and also today, but nobody has any real evidence that the issues that Morphy and Fischer experienced were as a direct result of playing chess.

I can definetly assures chess gives frustration and its mostly experienced by top or professional player even International master committed suicide as he was not able to play his best form 

Chess is very competitive and in Fischer's day there was an awful lot of outside pressure directed at him.

He didn't do much to help himself of course, but that was Bobby.

I’ll echo AceFrawley’s comment. Playing chess doesn’t cause mental problems. Look at all the people who play chess who don’t have mental problems! It may be things associated with playing chess, but not chess itself.

How many professional players do you know that you are basing this theory on?

English IM Bill Hartston  once wrote: "Chess doesn't make people crazy, but sometimes it helps keep crazy people sane."

Reminds me of this:

”Does your husband suffer from a mental condition?”

”Oh, no; he enjoys it!”

he lived for chess so it's poetic that he dies for chess

This is for you even google his name once 

Vitolins suffered from schizophrenia. The disease first showed itself in his late teens and he struggled against it for years before he finally took his own life, It is a gross oversimplification to ascribe his suicide to mere "disappointment" There is a very sympathetic portrait of Vitolins, and some other Soviet-era players who suffered from mental illness in the book "Russian Silhouettes" by Sosonko.

And this gentleman isn’t even bringing up how chess turned Emil Deimer into a nazi.
