Errofluid

Errofluid is a neurogender defined as "a gender which is fluid or fluctuates in relation to psychotic symptoms".

An example is when someone’s psychosis symptoms are strong and having a manic episode they feel genderless, when they’re strong and they’re having a depressive episode they feel more male.

However, the term errogender can be used regardless of how one's psychosis affects their gender
