This is one of those things that if you actually thought about it yourself you would of come up with the same answer but here it is they’ve actually done some studies and figured it to be true. From the BBC:
Creativity is often part of a mental illness, with writers particularly susceptible, according to a study of more than a million people.
Writers had a higher risk of anxiety and bipolar disorders, schizophrenia, unipolar depression, and substance abuse, the Swedish researchers at the Karolinska Institute found.
They were almost twice as likely as the general population to kill themselves.
The dancers and photographers were also more likely to have bipolar disorder.
As a group, those in the creative professions were no more likely to suffer from psychiatric disorders than other people.
But they were more likely to have a close relative with a disorder, including anorexia and, to some extent, autism, the Journal of Psychiatric Research reports.
You have to wonder though, if the doctors find cures for all these illness’s, what will become of the creative person?
