Your chances of showing severe ADHD symptoms increase exponentially once you're through menopause. Is it possible that your symptoms are related to potentially having this disorder in a newly severe, post menopausal form?

Not sure if it's helpful, but you could consider looking into ADHD coping methods (outside of medication, since it sounds like you don't have access to that kind of healthcare at the moment). They may help you to find a better balance.

Regardless, my thoughts are with you and I hope you find fulfilling, profitable work and a happy, comfortable home life soon!
