Realization of ADHD & I'm heart broken!

At 30 years old I thought I would be a female titan on Wall Street of the finance industry, instead I am grappling with underperforming and underearning each year as I get older. As the years quickly pass by I dig myself deeper and deeper into debt and have no future prospects of employment, marriage, or anything that would be me closer to financial security. The only thing I can think of is my quick witted mind that processes material at the lightening speed, but fails to assist me when I actually need it. Having ADHD sometimes feels like I'm a undercover superhero, but in times of distress when I am suppose to use my superpower I can not because I either forgot the combination to the lock in my mind or I am over processing material that it has exhausted me in which I am too tired to assist.
