Has anyone else felt stupid after telling someone they have ADHD?

Not that it's really surprising but I blurted out in the middle of a conversation that I have ADHD and that I'm trying medication to see if it helps. The two people sitting across from me said they were sure they had ADHD so I guess I thought it was safe to open up to them. They looked at me puzzled and then the one said "I don't need medication, I'm happy the way I am." and that was that. I felt really dumb. The one lady is my friend and she is is in her late 40s. I'm 23. I felt like the undertone was, you don't need the meds, your lazy.. or something like that. It felt weird anyways. Made me wonder though, are they fooling themselves or do the really not need them? My friend that's in her 40's, lets call her Kate. Kate has 2 children, (the other participant at the table was her kid), lives alone, has many of the problems associated with ADHD, has a job at walmart, had her own business but couldn't make it, seems generally unhappy but she has never considered getting help for all of her struggles. She told me she wants to go to school but at her age, her brain just doesn't do learning. Her kid is young, has ADHD and is getting married. She doesn't have an education and doesn't ever plan on getting one. She's extremely fidgety and obviously struggles, but says she likes it that way. Do you think they made a well informed decision to not try medication or that they decided to settle for less in life. I certainly can't handle what my life has become. What's everyone's opinion on this? When do you know when to tell people you have ADHD? Is it better not to? Have people judged you when you did?
