I agree that you could probably find things that interest you AND can help you. Have you ever taken those test that show your abilities in certain areas? Princeton Review online has a free one. I have taken a few and they always tell me that I need a job that makes me feel like I'm making a difference like a doctor, nurse, teacher etc...

That might help you figure out which areas you might be best at, then you might be able to talk to a counselor about how to combine those practical aspects with the things you love. Personally, I know I want to teach. I have always loved teaching and helping people. Then I found that I was pretty interested in insects and biology. So I'm taking what I love (teaching) and getting there by practical means of biology.

So if you like helping people and you love art...you could turn that into something like an art teacher. Or working with special needs children as art therapy like others have said. There are always ways to get some practical out of what you love.
