One thing that I think is important to know when you’re talking to someone with ADHD is that we often genuinely forget why we’re feeling/acting a certain way.  It’s common for us to see something upsetting that puts us in a poor mood and then forget what that thing was twenty seconds later… but that poor mood remains.  So if you ask us what’s wrong and we go “I don’t know!!” I promise that’s not us trying to dodge the question or otherwise be annoying – we often, genuinely, don’t know.
