I want to mention something..... this is how im seeing your story. You probaly came there with the intenetion of getting better, you were a bit aprehensive at first, but then kinda came around......and thennnnnnnnn.... you wind up WORKING???? The place that was supposed to be safe, give you a break, time away, and support to get better, winds up presenting you with a situation that made you instinctivly respond. It's not supposed to happen there, give yourself some credit....you were blindsided. Hopefully, sistuations like that wont become common there....
good luck with the new program, you seem positive and optomistic about it and thats great!!
