wave of nausea and with dark cloud descent

i saw a post on facebook (right on the front page, i wasn't even looking into it.) from a friend remembering a child's life cut short. of course it had a picture with a baby (with bruising?) the dark cloud descended and the nausea rolled in. things like this make everything come back in vivid color. to think that people intentionally hurt children... it has to be one of the worst crimes of all. it's all so horrible... even to think that there are those people out there. it makes me sick.
Then I remind myself- in my line of work, I cannot put myself in the place of everyone who is losing or has recently lost a spouse, parent, family member, or friend. There will come a time when I will have to experience those thing. It does me no good whatsoever to put myself there. That is not my pain or grief (When we a Resident passes away, I may experience my own loss, but it's detrimental when I think "what if I lost C?" "what if I lost E?")
In these cases I have to remind myself- "that is not me. It's not my family. Those people will have to face their own Time of Judgment. I can only do my part. We will raise a happy, healthy child and do our best to be wonderful parents. That is who I am, that is what I can control. I cannot control the unhappiness of the world, I can only do my part to make it a better place."
