So I worked (well till monday 30.11 still working) for a lady in a wheelchair.

if you are going in to private care, make sure you really look at your contract.
Make sure you are allowed to know and have exchanges with your co workers even if you do not ever see them
Talk to your employer (client) how to handle emergencies, and make sure you have all important contact information.
Do take care of yourself, keep personal and your job separate (self care)
Its a tough but rewarding job
