ADD/ADHD?

For those who have it, what does it feel like to have ADD/ADHD?

When I was younger, my parents were told it sounded like I may have it, but they never really confirmed it. I’m 17 and a high school senior, I notice a lot of symptoms that fall into it:

*Fidgety - I give myself pimples all around my mouth bc I always rub it

*Short attention span - I always have late assignments bc I can’t focus

*Always moving - even my mom notes that I don’t stay in one spot for long

*Losing things - I’m always losing my headphones, glasses, work hat, etc

*Don’t stay on topic - I always want to talk about something else, completely off topic, before even finishing one conversation first

And a few more but I just want other people’s opinions.
