There are ways of putting across your concerns without inditing fear and suspicion - but ultimately if people don't want to listen they don't want to listen. Really it's your Doctor you should be telling this too. Someone will have to put in a request for/arrange hospital admission and it's usually a GP or family Doctor. Even if they're just aware that you're not in a good place, it's important someone with authority knows of your position.

As for family and friends, just keep it simple. I find the more you have to repeat something the more likely it falls on deaf ears. So just state once, for the record, that you're usually very good at managing your symptoms and getting on with life but now you're struggling and would like to feel supported as you can't cope with something like this alone.

If they listen, great, if they don't - focus on addressing that information elsewhere like, again, your Doctor. Someone will have to listen to you eventually. Please know that people here do understand you and can only advise that you keep going. Although we shouldn't have too, sometimes making a nuisance of yourself is the only way forward. Unfair, but true.
