Hi Classic Fm and welcome to the forum.
I am carer for my husband who was diagnosed five years ago. We found great help and support from our local Parkinsons' Support Group. They also had a Carers' Group, which I found very helpful. Not all Groups have a Carers' Group but it would be worth finding out. Or the Carers Trust may have a local group.
You will find lots of advice and support on the forum. And it is a good place to vent your feelings as well, should you need to.
