Is there a difference in always knowing & just finding out

Okay so I have lived with ADHD since I was a child, I have always known that I was different, that my brain didn't work the way all the other kids brains worked!! I am wondering and would like some feed back on whether you think it is harder always knowing you have had it, or finding out as an adult. I know that low self-esteem goes with ADHD and that it is something that can be changed ( I am working on it), but I wonder if it would be easier to work on had I just found out, or if always knowing is easier, because at least I had a reasoning for all of my behavior and thoughts. I must say that over the last few weeks I have really started to learn as much as possible about ADHD and there is so much I didn't know, and so much more is starting to make sense. I now understand why I constantly do the things I do. Alot of the "scatterbrained" things I did, I always understood but so much I didn't. I also want to thank everyone on here. I never talk about my ADHD with anyone and I don't know that I have ever meet another person with ADHD that I have had a conversation about it with. It is so refreshing to knwo that there REALLY are other people out there like me, and that I am not alone. Althought it so often feels like it.
