I have heard of hard days....... without you the world would be of a lesser quality.... hope you do but talk to your supervisor.maybe taking a short leave will allow you to recapo and rebuild your strength. debreifing is important for you guys after dealing with many many patient.... it sure can take a toll....... talk to someone though....if you question this.... might be a sign of burning out........ it is very common...... take it seriusly but do force yourself....... your day might be a great one..........
