I was diagnosed in jan 09 with my first hospitalization. I started showing signs in 8th grade. No need for sleep I had my first major depression at 17 thet tried me on all sorts of antidepressants but I couldnt take them they made my skin crawl and what i didnt know then but they also started hypo so I quit them. First full blown mania was 2009, I think. Probably younger with being delusional just never got help for it, but only srarted hallucinating in 2009.

So if I was bipolar at age 14 that would be 19 years for me.
