I can obviously only tell anyone here about me - I cannot, and would, not speak for any of your DMs.
I am in my 60's. I have never felt that I fit in properly with others in my age group.
I am a mother and a grandmother (and a wife if that is important in this particular instance).
I did my best to be a good mum - hopefully most of us do.
Unfortunately, I now know that even though I loved, and of course still love my Dear Children so very much, I was not a very good parent, some of which was probably down to my very low self-esteem. I do believe that I was a kind person, and tried to be helpful whenever possible.
But now, I have some health issues, which of course the older one gets, then the more likely we are to suffer from less than brilliant health. However, for about the last 1.5 to 2 years my personality seems to be changing greatly, and it both dismays and terrifies me. I used to be so loving and caring and patient, and now I am horrible and nasty, and certainly don't suffer fools gladly - which includes me, I don't suffer me lightly either.
I have so far been able to mainly mask my feelings from my Children, and as far as my young Grandchildren are concerned I (Thank God) am still loving and caring and patient - I pray that that will continue. But very sadly, and horrendously, my poor DH gets the brunt of my awful behaviour, and to some extent so do some medics. Apart from that, I don't really mix with other people - lucky them! I don't know if I have the early stages of a dementia, or if I am just a really horrible and nasty person, whose true, or old age persona, is now pushing through. I actually hope it is a dementia so that my loved ones can have an understandable, and hopefully bearable reason for my apparent change in character.
I do hope to be able to see my GP quite soon, but like most of the rest of the country (it seems), getting a proper appointment with a GP for other than a serious emergency, seems nigh on impossible. I am under a neurological consultant for something else, and have an appointment to see him quite soon, I wonder if he would mind me telling him about this, as this change in my character is not part of his speciality as far as I know.
Anyway, to those of you whose ageing parents are showing very different sides of their personality, please consider that it may be due to some new illness or condition, or I suppose even the normal ageing process. If you can reasonably easily do this, please encourage - and help - your parent to see their GP. Thank God not all old people become horrible. Some manage to stay both gentle and sweet.
