Hello to everyone who replied to my post. Just to let you know I took the first step today and spoke to my GP and to Social Services. The GP is to arrange a visit from the Psychiatric Service who will assess my wife's current condition and advise whether any further medication would be appropriate. Social Services are to visit to advise me on appropriate providers of day and respite care in the area. To cap it all my wife has been really good today, just to make me feel really guilty. But I know realistically that she could 'turn' at any time. Well that's the first step taken and although my heart is now pounding I know that I will be able to cope with her behaviour over Christmas knowing that measures are now in place to change things. So thank you all for your support and advice, I'll be in touch and let you know what happens. Merry Christmas and best wishes for a happy New Year.
