What it can feel like
It might not look like sadness. For responders it often shows up as irritability, going through the motions on shift, losing interest in the crew and the calls you used to live for, drinking more, or feeling flat at home while still performing at work.
Why it happens
Repeated exposure to trauma, broken sleep from rotating shifts, and a culture that rewards "sucking it up" all stack the deck. Depression here is a cumulative injury, not a sign you are not cut out for the job.
What can help
Culturally competent clinicians who understand first-responder life make a real difference — many are peers themselves. Your EAP, a department chaplain, or a first-responder peer team are confidential starting points. Protecting sleep between shifts is treatment, not a luxury.
