The confusion is about you receiving the full support of your GP wrt Euthanasia.
If you are deemed to have full mental capacity to make decisions about your health then why are you in a locked ward, on a section?
Please do not take this as a criticism because it is not meant in this way. But, if someone was fighting for their right to die under the circumstances that you find yourself in - you may feel a little perplexed if a professional was agreeing with that person.
If it was a relative of yours I am sure you would feel a little anxious about this and on other hand if the staff are humouring you and you are colluding with this then I can understand all the complexities involved in this also.
It's definitely complex. The section could be lifted if I was to agree to stay voluntarily. My experiences so far also mean something. But it's a damn long and hard road, but I do have full support from the team.
