At what age did you realize you had ADHD?

I was diagnosed with ADHD at 30. I tend to process many thoughts at the same time and can be emotionally sensitive when reality differs from my expectations. The one who told me to see a doctor is my wife who was really surprised that no one realized I have ADHD before. However I’m learning to better regulate my thoughts and emotions through daily meditation and mental log. It’s healthy but really slow. How about you guys? Any suggestions?
