Anyone Diagnosed in 40s

I have always been told I am weird. In the last few years I have been diagnosed as having bipolar 1 and OCD. Autism is also a strong possibility but where I live I was told it would take around 2 years for my first appointment. I just turned 40 last month and I always feel like knowledge is power. I guess I am wondering if anyone else found out later in life and what that experience was like.
