Momina Mela writes on the gendered misconceptions about confessional poetry. As she puts it, “In comparison to female confessional poets, male confessional poetry has been regarded with less ridicule as accusations of being merely therapeutic. This is often due to the detachment which occurs with the adoption of personas, even though female poets such as Anne Sexton, Sylvia Plath and even Sharon Olds integrate the use of personas in their work as well.” Also check out this Millions essay on the poetry of mental unhealth.
