Speaking as someone whose partner is a psychiatrist, popping in to echo that 1) it may or may not be ADHD, 2) only a doctor 1:1 can diagnose you, and 3) if it is, medication works wonders for many people.
It may be good to know that depending on the country where one lives getting a diagnostic can be a very long and laborious process. Online comments make it sound as something simple, it really depends on circumstances. But it’s definitely worth trying. Finding the correct medication is also not always simple, that takes some attempts, not everybody reacts the same way to a given molecule, and local scheduling laws can make it difficult to get access to the most effective ones.
