Some of what you describe is consistent with ADHD, though it could also be related to other issues, a different diagnosis, effects of medications or substances, physical health, boredom, etc. There are specific criteria for diagnosing ADHD, and this should be done by your doctor or a professional trained in ADHD assessment.

Pretty much everyone experiences times when they find it hard to concentrate, complete tasks, and/or sit still. What makes symptoms reach the level of ADHD is if they occur in more than one domain, i.e. home, social, work, school, leisure, etc., and if they cause clinically significant distress or impairment of function for the person.

If you are finding that the symptoms you mention are causing problems in living for you, I encourage you to see your doctor, or preferably a psychologist or psychiatrist specializing in ADHD for an assessment.

Good luck,
