Sorry, I've just replied to one of your older threads without seeing this one!
Again, I'm afraid I don't have any experience of that particular ward but I just wanted to say that the point of continuing your good efforts where you are currently is because "if you're not recovering, you're dying". I'm sorry they don't seem to be acknowledging your efforts but that doesn't mean you should stop trying. I guess even if you feel this week effort won't get you anywhere in the short term, not trying this week and losing weight just gives you more weight to gain back so in the long term recovery takes longer. If that makes sense?
Communicate as best you can and keep trying. That's the only way out of this.
