I always keep wishing they had figured out at test for mood disorder because every therapist I've been to has said I'm bipolar right of the bat, many friends have said it as well but my family doesn't believe so I never know who to believe. Pinning down a psychological disorder is so difficult because those who diagnose aren't with you all of the time and don't see all aspects of behavior and can only go on what you say which if you're like me, isn't everything.
