I am not an expert on the intertwining of creativity and mental health. But as a creative person, I went through my way of not losing my mind when being different.

The theory of positive disintegration by Kazimierz Dąbrowski helped greatly. It says that creative people have greater sensitivities and intellectual abilities than most; hence, their mental health issues are not the spell or the problem; they are the blessing. Just by realizing that, individuals can turn their mental challenges into being more efficient in developing their talents.

I found a few mentions about the theory of positive disintegration on Medium, but not all of them are accurate. You may want to look at introducing that theory to the Medium community.

The original writing about the theory of positive disintegration is in English.
