I would like to draw your attention to this new initiative funded by the NHS. It is a free knowledge and skills based learning programme. Some areas have group meetings. It appears to have limited groups in the South West region - Somerset. No wonder parts of Devon & Cornwall are still referred to as 'the withered arm'. (There was not so much money to be spent on the west which had to soldier on as best it could - left to wither away!)
I suggest you explore this link and see if Caring with Confidence would be of any help to you.
I like to meet and share problems in a group when I can but with time being such an issue it isn't always easy. Another problem I find is just how bone wearingly tired being a carer can be. It is so hard to explain to someone who hasn't experienced it. I often wonder whether it is a low grade form of reactive depression. Does anyone else have any views on this?
