I had an early onset. It presented as mdd at 14 but by the time I was 15 I was mildly psychotic and my moods were laible. I rapid cycled when I was younger but my cycles were much like today: shorter manias and long, crippling depressions. I'm 32 now and have had miserable, sometimes insane and almost always volatile moods, since I was almost 29. I was fairly stable prior to then for close to 8 years. I was diagnosed with bd at 15.
