With so many disorder Tiktoks around I can’t help but fail to spot the difference between having actual ADHD vs just having poor focus habits.
I myself have trouble focusing on tasks but I doubt I actually have ADHD given the recent surge of disorder Tiktoks - tho I do have autism - and that my focus is typically normal on tasks I devote to like gaming.
Focus is not the only symptom, did you read the list on the website I linked? Read the diagnosis section.
Also, autism and ADHD are commonly comorbid.
