Have been a full time carer to my DH for over a year since he had a massive stroke, has been a tough learning curve. But agree totally with all advice given, I get out once a week ordinarily to have a meet up with friends for lunch, a good neighbour we have known for years sits with my DH, I leave them both lunch.
We now have the higher rate of attendance allowance, do look into this and any other help you can get, an OT should advise on any adjustments you might need to make in your home in order for your DH to be more comfortable. This should be free.
Also look into local support groups not just for your DH but yourself as well.
We have a lot of help from the Stroke Association.
Have you registered with the GP as his carer, would advise this for it will help when applying for AA.
And treat yourself every so often, this might be a nice take away or subscription to Netflix etc., or just taking a long soak in the Bath with some lovely bathtime goodies.
