I always used to get angry after a vacation. It would always sort of take a couple weeks to get back into the swing of things. For me, it was because I would feel abandoned. And then I would resign to the fact that I was alone during the vacation, so I would be ok. But as soon as t would come, I would lash out, sort of like getting out all the hurt that as suppressed during the vacay. I think it's a normal reaction.
