As a fellow HA sufferer, with someone "wrong with me" every damn day, I've been given one simple piece of advice and want to pass it on.
Whenever you have the urge to google, which, if like me, you need to net-diagnose often, search "anxiety and your symptom".
So for me... anxiety and headaches, anxiety and numbness, anxiety and palpitations, anxiety and diarrhoea etc etc.
It's made me realise just how prevalent anxiety is with affecting us physically rather than someone intrinsically wrong.
