Someone close to me was recently diagnosed with ADHD and Oppositional Defiance Disorder (ODD). Holy fucking shit what a combination.

I can best describe it as their ability to focus only on things that spark their interest in the moment and an immense searing resentment when it is suggested that's the case.

But, having the diagnosis has helped us understand and help this person. Along with medication and therapy. If you have the means and think you might be this person, please seek help. It is life changing
