I use to work in ER, and when people came in with a Trach, that is a hole in the neck with a plastic tube in it, and have to cough, they would cough out all the sputum in there lungs, and it would spray every where. They couldn't help it. It would make me gag, and sometimes make me throw up. I never could handle that, also when we couldn't save someone, trying to give some comfort to the relatives, I would always cry with them. I didn't like to show that weak side when I was working. A lot of times, on my long drive home, if I was able to hold back my tears, I would let loose on my way home.
