What I told Potter about the Battle of Hogwarts itself is virtually ever-present in my mind, although I've carefully locked away the associated emotions like almost any other. Indeed, I've vowed to myself never to use Occlumency again, but I'll do whatever it takes to keep the feelings I've previously pushed away where they are. I'm safe as long as they're corked up. It's easier to live when they don't painfully knot my heart and brain all the time.
