I am so sorry to hear about your brother's death - and under such dreadful circumstances.
Reading your experience with the statutory services is so depressing. And no real prospect of change - the issue of social care is sorrowfully lacking from the manifestos we are hearing about in the media.
I so identified with your comment about nit being believed - it really does produce a gut reaction of blind fury - this is happening to me at the moment. First application for CHC funding was turned down (now being appealed) - one of the items in the refusal was that there was no evidence of OH's psychotic behaviour - there was: me telling them about it. They might just as well have written down that I am a liar.
Second CCH funding meeting last Tuesday - again the raised eyebrows when I brought this up. Yesterday OH in the nursing home was screaming and shouting and calling people evil b*****s, ringing me to say he was being poisoned and eventually rang the police to say he was being held against his will - I rang CCH bods and said will you please ring the NH so they could get the picture. I doubt they will.
Your post has really struck a chord with me (I expect you can tell!) - your battle mirrors mine and I really do know how the sheer energy required to fight just drags you down in the end. It is bad enough to have a loved one like your brother so very very ill; but to have to engage in frustrating battles to get the care needed is the final straw.
It is not just incompetence, but a system that is totally broken - when will someone get a grip on this?
I send heartfelt good wishes to you and your family. I hope that you can take some comfort from the fact that you did everything you possibly could and just the fact that you were fighting his corner will have been will have been a comfort to him.
I've got another 'keen'... Ouch!
