Back from the Recovery College. Treatment agreed with psychologist (not a student midwife or relative) for what is best referred to in the presence of lay people (that’s you) as Circadian Arythmia. 

They are very nice people. There might be one in your area. Look, they have courses on anxiety, mindfulness, dealing with stigma, all sorts… 

Don’t worry. I’m not taking the course on assertiveness 😛
