Hello
@Kazza5 and firstly welcome to this friendly and supportive forum. There is a wealth of shared experience of dementia here, so I am glad you have found us.
I am sorry to read about your husband's diagnosis. It's tough for sure, to get the diagnosis, even if you were half expecting it.
What's ahead is difficult to predict, which makes it all a bit scary. I totally understand your worries and anxieties. Try and take each day as it comes, and so you can enjoy, as far as possible, the here and now.
In practical terms, if you haven't already, it would be wise to get Lasting Power of Attorney organised for both the Property and finance one, and the health and welfare one, as this will make things easier for you further down the track.
How to make a lasting power of attorney (LPA): starting an application online, choosing an attorney, certifying a copy, changing an LPA.
