These events include violence, poverty, workplace stress, hormonal factors and impossible beauty standards as well as infertility and the losses experienced in various relationships. Sadness and depression are a continuum. Sadness involves a lot of feeling. Depression is a flatness. There certainly are cross-overs.
Depression is a point beyond sadness.
Sadness is sometimes mobilizing in that it can make you feel something. Depression, on the other hand, is immobilizing. I didn't call the book Women And Depression because I don't like medicalizing moods. It doesn't do justice to a lot of people. Essentially, when it comes to women and depression, depression has social causes.
