I have a hard time concentrate, or when im haveing a group conversation i space out? is that mean i have adhd

Possibly : Certainly good be. I'd discuss it with your physician.

Not neccesarily : It happens to many people . Just because you are experiencing those two symptoms it does not mean you have ADHD . There are other factors to consider. In order to make that diagnosis you need to be evaluated by your doctor or psychiatrist .

Not necessarily: There are many medical conditions that can cause such symptoms. For example, fatigue from not enough sleep.
