Respite is designed for parents / carers of those with higher needs, especially alzheimer's, dementia or severe mental disability.
Its basically to give them a temporary break to relax, they take the person being cared for away somewhere usually fun like a park for example or in the case of dementia a home where they sit in a circle sing a few songs etc.. then get taken home.
It might just be an automated mailing nothing personal to or about your functionality by saying you have severe symptoms or your parents need a break, your parents probably are registered somewhere as a carer & were notified that its there if they need it.
