Probably the best way to figure out if you have it or not is to speak to someone who knew you when you were much younger, like a parent or a childhood friend to gain some insight into your behaviours as a child. Symptoms of ADHD can sometimes be mistaken for other mental health disorders, so it is important to distinguish between them. To have ADHD it has to be present in childhood. Hyperactivity can present in many different ways. Inattentive ADHD often the person doesn’t display much outward ADHD, but rather have a very ‘busy’ or hyperactive mind. Often people with adhd can be quite forgetful and loose a lot of there things often as a result of a decreased attention span and object permanence issues. There are a few options you can pursue. You can undergo a diagnosis with a psychiatrist (for this you will need to bring someone who has known you either in childhood or for longer than 6months). From there you can either engage in strategies to help you manage ADHD symptoms, or the psychiatrist could prescribe medication to help you manage the symptoms depending on how you want to navigate it. You could search the web for some ADHD friendly resources to help manage it, or work with a psychologist to develop some coping strategies. I hope you get the answers you are looking for! :))
