I think the only thing you can do at the moment is accept that it WAS a horrible experience. Nobody can expect you to be ok right after that.

I am so very sorry that you had to experience that, sorry for that guy but especially for you.

As to remembering or writing down I am not sure: these days it is said that push a traumatic experience aside in the first time after it can help just as much as talking to a doc or psychotherapist.

Try to be gentle to yourself: try to take stress out of your everyday life. Play with the furkids, take a hot bath (if you like that.) or cook yourself a nice warm soup (if you like that).

Good old time will change things- but not right now unfortunately.
