If you were diagnosed 6 months, did the doctor(s)say you might have a biochemical deficiency in your brain because you are missing some chemical that helps you cope? For example, people who take risks and people who like danger like parachute jumpers are missing a neurotransmitter in the brain that talks to other brain cells.
Before you were born, a black, religious crusader, Jesse Jackson, preached to young blacks that they need to say to themselves that they "are somebody" and repeat the phrase several times a day. After all, America did not give black slaves a chance after the Civil War to improve their conditions like education, jobs,etc. The phrase helps to allow blacks to believe in themselves and repeat the message over and over. You need to believe in yourself regardless who may be against you or how bleak the future looks for you. Use the power-of-suggestion to demand your brain accept your commands. In college, I demanded my brain awake me at 7 AM for a class. It took three days of my telling myself to be certain to awake me. I awoke two minutes to 7, and I still practice the suggestion when I need to remember something important.
