I wanted to just say a big thank you to everyone who has taken the trouble to respond to my "explosion" of 2 days ago.
To those who responded by saying I should not put up with it, thank you for the positive suggestions - I should have explained the background a bit more, but I was, I admit, feeling pretty cross at that moment - I am sure that came across very clearly! Your responses were understandable as I realise from reading back over my OP.
To those who remember the background (and I am impressed by your brilliant memories!), thank you for your understanding and kind responses.
As has been pointed out, my OH has a history of anxiety problems, and this can also (and is with him) be an effect of PD - so we have a double whammy here.
I know that there are others who are going through similar, and often much worse, problems and thank you for your kind posts.
ann has summed it up so well - what do you do? You are living with your life's partner who has changed so hugely - you just stick by them and tick along as best you may, as indeed they would for you if the circumstances were reversed.
It did help me enormously to "blow up" on here; it stopped me directing it elsewhere!
I also anted to affirm, as has been said upthread, that anxiety, dementia, depression etc. are common results of PD, but they do not happen to everyone and many people tick along well on their medications - as indeed in some ways my OH does. Without the modern drugs for PD he would be far far worse than he is, so we are thankful for that.
Thanks to everyone and 3 cheers for Gransnet!
