Keep in mind that ADHD is most likely a combination of a number of different factors that'll lead to a diagnosis. Many people exhibit one to even a couple of the factors, but that doesn't necessarily mean they have ADHD.

But if you look up some of the checklists or videos for "do I have ADHD" and seem to fit the bill of quite a few of the factors, it's worth talking to a therapist or psychiatrist who specializes in diagnosing it. There are many people who slip through the cracks in childhood, a lot of times because schools and docs are looking for the Hyperactive side, but many times the Inattentive side gets dismissed by a number of different excuses.

And as others mentioned, if you are diagnosed with it, that doesn't necessarily mean drugs or even therapy, but it can mean a better understanding of things you might struggle with and the reasons for that, which can better prepare you for coming up with healthy strategies rather than negative/unhealthy ones.
