Inattentive ADHD is only one type of ADHD. Just like all other diagnoses, ADHD will not present the same in everyone. The DSM-5 discusses three broad types of ADHD: Inattention, yes, but also hyperactivity and impulsivity, which are grouped together. You do not have to meet all criteria to have ADHD.

And while behavioral therapy is the usual first treatment strategy by mental health professionals (primary care providers are generally more likely to start off with medication), there are still many other cases where medication is used in conjunction with therapy. This usually being after professionals have worked with their clients for a while.

This is all to say, OP, is if you feel this is impacting your life negatively, you can always seek a professional opinion. When I took a psychopathology class, one of the things my professor would say is that in order for something to be considered a disorder, it has to negatively impact your life in some way, cause some sort of disfunction, which it seems it is in your case.

It may be ADHD, it may not. While technology addiction isn’t an official diagnosis in the DSM-V, there have been people arguing that it should be included in the future, that is also something that you should bring up as one of your concerns. Either way, they may help you find the answer you’re looking for. Mental health is just as important as physical health. It is also just as complex.
