Hi there Locky,
as Peanutz and Silly have said, blog about it.
I know its a cliche however time is the only element that adjusts your view of the world and your diagnosis. Its difficult at the time of diagnosis because you are overwhelmed by information.
We (c/connections) are ordinary people like yourself and we all understand.....just blog away and say everything and anything. There is no judgement here.
One thing is for sure though, you will take 2 steps forward and 10 steps backwards.....however you are moving forward slowly......keep the focus on moving forward.
Oh most importantly, be kind to yourself.....don't push yourself, love yourself with your grankids, walking or hobbies. It doesn't matter if you can't concentrate for too long, the important step is that you applied yourself....
Also stay away from the internet. Your diagnosis and treatment is individual like you. Stories on the internet are other persons individual diagnosis and treatments....trust me, I scared the life out of myself.
Take care
