Is this an ADHD trait or just a general (unpleasant!) character trait?
Is 'clamming up' during stressful or difficult conversations linked with ADHD or is that just an individual character trait?
For a long, long time our 'conversations' have consisted of me talking and him supposedly listening. Even serious conversations about our ill daughter evokes the same response. Total silence. He will get off his chair and walk round the room or stretch or do something else physical but there is no verbal response.
