This might be going to day care or attending school.
If possible, make sure that the person you care for carries on with the activities they have always done, such as going to church or going to clubs and groups.
There may be new groups or activities that the person you care for may be able to take part in. There are lots of support groups for different conditions and disabilities. For example, there are many 'Singing for the brain' groups for people with dementia and their carers. Have a look at this video about Singing for the brain from the Alzheimer's Society.
The person you care for may be able to go to these groups without you. Even if you go too, it is a chance for you to talk to other carers and perhaps have a bit of time to have a quiet cup of tea.
Contact your local carer service to see what is available near where you live.
