Adult ADHD?

Greetings.

It's been a while since I visited 7Cups and this group, and wanted to come to ask a question.

Are there many here who have received a diagnosis of ADHD in adulthood? I'm asking because the question of whether I may be ADHD came up recently during a counseling session, and I've been looking into it. Based on the self-questionnaire I've looked at, it's very likely.

Would like to get a sense from those who are over 40 and were diagnosed - how helpful has it been knowing that you have ADHD, and what tools are working for you?

Thanks :)
