Here's my theory:
Everyone is at least sometimes unstable. Some people hide it. Some people show it.
Artists, I think, are more likely to be in the show it category.
Not all people who show it are artists, and not all artists show it.
I've dated several artists, they were/are all unstable and all incapable of hiding it. I like that in a person, so I kept the last one I found
Congratulations on flipping your life on it's head to follow your bliss. You won't become un-date-able, you'll just have an easier time wading through the bad matches
