Just want to add my voice to the many who have already said: thank you for sharing this. It must have taken some courage.
My own experience has been similar (though I’m far less qualified than the OP).
I’ve recently graduated from one of the top ~10 universities worldwide, after investing heavily in EA throughout my studies. While a student, EA was the biggest thing in my life. I read a lot, and several of my EA peers told me I stood out as particularly well-informed about EA topics, especially long-termist ones. Eventually I contributed some of my own research too. I also invested enormous amounts of time in student EA projects. Many people, including ones I thought well-informed about the talent landscape, fully expected that I would go work for an ‘EA organisation’. Naively, I believed it too.
Over the last seven months, I’ve made over 20 unsuccessful job applications (I keep a spreadsheet). This has increased the severity of my depression and anxiety. Over time, I began to shed my identity as an EA, no doubt as a self-defence mechanism. Now I’m very disillusioned about my ability to contribute to the long-termist project.
