It’s not daft, danman was explaining it to me on a previous post about triggers, and it started to make sense as I had noticed when my husbands particularly bad with it he would be listening to a specific singer. Its funny how so many people are affected in the same way and we can all see what’s happening but we don’t know what to actually do to make it better.
Yes I’m sorry to say I understand your wife acting that way, it’s so upsetting to watch someone you love doing that to themselves, and we can’t make any sense of it ourselves.
