I am also so sorry about your loss. No words can express to you the sympathy I feel for your situation. I do not believe there is any set time limit for anyone to grieve or a "reasonable" time for you since this was such an unexpected loss. Likely for years to come, due to the work we do in the ER, you will face patients who will bring about triggers for you that may make you have to excuse yourself to the med room, breakroom, bathroom, or wherever you need to go for a few moments to compose yourself. You are human. As long as you work with understanding people, you WILL make it through this. ER nurses are some of the toughest of our kind. Don't try to rush yourself though. Just try to live through this new experience in your life. It is an awful one, I am sure, but it sounds like you are headed in the right direction since you are looking for ways to make it to the other side of it in one piece. Counseling for your children is wonderful, but don't forget about you too.
