You are a good man for helping these people in their time of need. Seeing a traumatic event like this is serious so please make sure to talk about it with your friends and family so you can process it too. My father in law is an EMT and fireman and they always make sure to talk it thru with each other after these types of tragedies. The last thing you want to do is keep it in. Thank you for sharing, and thank you for being a stand up guy who was willing to help.
