Do U feel better after U diagnosed with ADHD?

I’m a 50 year-old female. I was just diagnosed this past year. I’ve strongly suspect that I had ADHD since I was 23 years old, but because all the research was done on male children, it all said that I didn’t meet the criteria. Knowing that I was right all this time and but there’s all these tools out there to help me cope and to explain the way I am does help, but it doesn’t solve everything.
