Perfectionism? Addiction? Mental disorder?
Associating perfectionism with a mental disorder sounds a bit strong.
Perfectionism is not a “clinical term” so I don’t think it is the thing to do anyway.
But, perfectionism can be addictive and self destructive, yes!
If being a perfectionist ruins your life and makes you totally disatisfied, it can be seen as a form of addiction.
It can be a form of positive addiction too if it is a mind pattern which helps you perform better in life for instance.
