Hello Graham and welcome to the site
When you are ready perhaps you can tell us more about why you are confused and angry.
I do get confused and muddled and I suppose I do get angry with myself for not remembering stuff, losing things, and not being able to take in much new information. However after nearly 3 years, some counselling and this site, I am now more able to accept these things and even laugh about it at times. I think now it is more frustration at not being able to do as much as I want to do.
The positives are that I am much more mellow and actually enjoy my life more, I have taken up photography which helps in a few ways. I can look at my photos and that helps me to remember people and events, I see things differently post SAH and look in wonder at trees, skylines etc, so take photos of these things, I am also learning a new skill, albeit very slowly!
Take Care of yourself
