As a woman in society, it would be quite unusual to have never ever experienced any form of sexism.
From leering, uncomfortable catcalls, wage inequality, and being forced to continue with unwanted pregnancies (thanks for that one Ireland), it's no wonder that The World Heath Organisation has indicated that gender specific factors have a negative impact on female mental health.
'Depression, anxiety, psychological distress, sexual violence, domestic violence and escalating rates of substance use affect women to a greater extent than men across different countries and different settings.'
'Depression, anxiety, somatic symptoms and high rates of comorbidity are significantly related to interconnected and co-occurrent risk factors such as gender based roles, stressors and negative life experiences and events.'
'Pressures created by their multiple roles, gender discrimination and associated factors of poverty, hunger, malnutrition, overwork, domestic violence and sexual abuse, combine to account for women's poor mental health.'
'Gender specific risk factors for common mental disorders that disproportionately affect women include gender based violence, socioeconomic disadvantage, low income and income inequality, low or subordinate social status and rank and unremitting responsibility for the care of others.'
The World Health Organisation goes on to point out that sexist elements of society can dictate not only how women feel in regards to mental health, but also hopw those issues get treated in both men and women.
'Gender stereotypes regarding proneness to emotional problems in women and alcohol problems in men, appear to reinforce social stigma and constrain help seeking along stereotypical lines.'
'They are a barrier to the accurate identification and treatment of psychological disorder.'
So I guess those 'wow, she must be on her period' or 'calm down, you're just being over emotional' comments were wrong all along (not that we didn't know that).
As it turns out, societal sexism can be a contributing factor for a women's mental health.
