I am 47 and finally diagnosed as bipolar 3 months ago. I'd say I have some experience hiding symptoms. I'm new to the forum and I suck at articulating my thoughts. This diagnosis is overwhelming me ATM. I think in my case, self medicating, having a non confrontational wife, a job that gave me freedom and mostly hypo-manic phases kept me within the realm of a "normal" perception. That all changed when I hit 40, quite drinking and my job brought me into the office in a professional type setting... I'm struggling now.
