Yeah, unfortunately, that happens sometimes, too. You seem to be doing everything right, but still something goes wrong and you lose a seemingly successful deal. You have to be prepared for that at all times. Yeah, it's unpleasant enough and even a little depressing, but it's trading. You have to always be alert and literally ahead of events. It sounds a little pompous, but you can handle it. Think of it as part of your learning. Mistakes are lessons too, you can learn from them.
