I am puzzled that you went 14 days without eating before you called 111. My DH has very serious heart problems. If he went without eating for 3 days, I would be on to the doctor immediately.
I do understand how difficult life is when you are seriously ill, as you obviously are, and it is so easy to see everyone who is concerned about you as being less than helpful.
But knowing what I am like when I am unwell and people fuss around me, I think what you have is a genuinely concerned family worried that your illness and anxious nature are making your behaviour erratic and that your dealing with the nitty gritty of the medications you take is eually erratic and this is doing your overall mental and physical health no good at all.
Can you see your GP or nurse to talk the whole thing through and find a way of working with your family so that you are able to be calmer and they can know how to help you.
