Yup, take care of yourself and don't ignore those instincts of un-safety. You gotta have someone to talk to about them that you trust, otherwise things like that can eat you alive. All the tough character and training in the world can't reverse the fact that trauma sticks in human brains, and the worst thing you can do is pretend it's not there when it clearly is. And while I've never been in service as such, trust me, I can speak from personal experience on that.
And a massive respect to you and the other service veterans here. Thanks for doing what you did, whenever and wherever you served
