Hello
@Mandyboo and firstly welcome to this friendly and supportive forum from me also. There is a lot of shared experience of dementia to be found here, so I am glad you have found us.
I am sorry to read about your Dad's diagnosis. It's tough for sure even if you were half expecting it.
Please do have a good look around the various sections of the forum and ask any particular questions you may like to. This is a good safe space to share only what you want to; and I know some members find it helps just putting things down on here sometimes. Members here really do understand and want to help.
