Hope it goes okay for you Lloyd. I think we all deviate from 'normal' in some way and I suspect I could be diagnosed with something, but I'm not sure it's causing me problems for now. I am not sure I want to start reading about it as that may convince me I am worse than I am. Anyway, if drugs can make you function better then go for it. I am conscious that various aspects of my health are on a downward slide now as I'm a similar age to you. I hope to have many more productive years and will do what I think is prudent to optimise them.
Stay well.
