I can understand this quite a bit. I'm a person who doesn't really mind it but choose not to engage in such a thing mainly because I'm not really like that as a person.

I just prefer hanging out with friends and talking with them or heck even play games and that's about it.

If you do have a friend who has ADHD, have patience, they don't mean to sound like downers or not paying attention to you, they just can't help it~

Best natural medicine I can recommend is love and support, make them feel they can push on and be motivated and they do matter!
