You might be able to ask family and/or friends to help you for a couple of hours a week or even for a day or weekend.
Resources to help you
It is better to ask, then never to ask at all; you might be surprised at who is willing to help.
To help you communicate your needs clearly Being Heard by Carers UK gives you tips on how to do so.
If you have a list of willing and ready helpers then the Jointly App by Carers UK can help you to organise and share care among your family and friends.
