It was World Mental Health Day this week — and it drove me mad. I don’t have ‘mental illness’. I have bipolar disorder, and I feel as possessive about my diagnosis as Gollum did his precious ring. One term. One label. To lump the manifold terrors of the mind together under the monolithic ‘mental illness’ is an offence against the person. Failing to differentiate shifts the stigma like a bubble under a carpet. So I was horrified to discover, in my latest stint in a psychiatric hospital, that others experience exactly the same as me. Others use the same ‘maladapted coping mechanisms’. They are also their own worst critic; they replay their mistakes; they are wracked by ‘meta-worries’: being worried about being worried.
