A Pew study from 2020 (but one I just now came upon myself) reported that the more liberal you are, the more likely you are to have a mental health condition.
The worst suffering group are white females, ages 18-29 where over 56% have admitted to be described by their own doctors as having a mental health condition. Conservative females of the same age group suffer at less than half that number (27%).
While women tend to have more mental health problems than men (don't be mad at me for saying it, this is what the study reports) it is notable that liberal men have a higher percentage of mental health conditions than conservative women in the same age group. It is also notable that those who describe themselves as "moderate" (neither liberal nor conservative) suffer mental health issues in the middle numbers between each of the groups.
There is no way around it: regardless of age and gender, the more liberal you are, the more likely you are to suffer from mental health issues.
