Thank you. I think the anorexia is mainly a result of the depression. Her blood got checked a few months ago and everything seemed fine, but there is surely room for improvement. She eats very little meat, maybe she has a iron deficiency.

The main reasons for the depression seems to be the death of her father and the chronic pain, wich showed up long before the depression. Maybe there is also a genetic componence because her mother says about herself, that she has also very often "low mood". But she thinks it's just the way things are.

I will read up on vitamins. Do you think you can trust wikipedia in this respect?
