I worked overnight in the ICU. (warning:sensitive content)
When my shift ended a patient suddenly became restless. She had fluid in her lungs. Sadly we can't do anything about it because her kidneys don't work. I was extremely exhausted. The morning doctor had taken over already so I left the rest to her and went back home to nap before going back to work. After 2 hours of sleeping, I woke up with the memory of the restless patient, trying to catch her breath. It suddenly made me short of breath myself, suddenly I was gasping for air. Had a panic attack. Quickly took a medicine to subside it. But damn. ICU is so stressful. It is affecting me in ways I didn't know I was even sensitive to.
