My response to the above article from NPR:
Depression is the word people use when they feel bad. What people in this piece are struggling to understand is that depression is not one thing or in fact “a thing” at all. It’s certainly not a useful diagnosis. DSM diagnosis constricts our understanding rather than enhancing it. Here they are struggling to understand states of arousal, and they lack the words for it. High arousal will lead to anger outbursts and ambient fear, as well as crippling shame, and people will describe themselves as depressed. They feel bad.
In this article, the depressed person with anger outbursts comes to understand the impact of childhood trauma on her state as an adult. Trauma was the issue- it left her disregulated. Therapy helped. Therapy with neurofeedback would help even more.
