"Occasionally, someone with anorexia may refuse treatment even though they're severely ill and their life is at risk.
In these cases, as a last resort doctors may decide to admit the person to hospital for compulsory treatment under the Mental Health Act. This is sometimes known as sectioning or being sectioned."

That's a quote from the NHS website http://www.nhs.uk/Conditions/Anorexi...Treatment.aspx

It seems clear section would be a last resort. The trouble is, hunni, is that it doesn't matter what the reason for you not eating is, unless you start eating you're going to become severely ill so they have to prioritise that regardless of whether it's anorexia or depression. If you don't want to go to hospital, you have to eat and keep sustaining a gradual weight gain.
