My Mum works as a care assistant, it would appear to be an 'interesting' job to say the least.
Do you like computers? If so you could dabble in something like web design. From what I know of it I think it would fit your criteria well.
Failing that, do you like drawing? Before I came to Uni I spent two years drawing storyboards for a local animation company. I was able work wherever I wanted, alone, and doing something I enjoyed.
Maybe those suggestions will give you a couple of ideas.
