Selfitis

I've been reading in the newspaper that I may have the mental disorder “selfitis” which apparently is “the obsessive compulsive desire to take photos of one’s self and post them on social media”.

I suspect my problem could be 'borderline' rather than 'acute' or 'chronic', but it's more likely to be imaginary because it's that wretched woman, the Mrs, who insists on taking them.

I wonder what her mental disorder is called.
