Do you have access to a computer? I would proceed with caution, but maybe, try something online. But like I say, be extra careful--there are A LOT of scams out there, especially those get-rich-quick scams... Also, I don't particularly know your situation, especially your family set up, but is there any extra money you can make working (i.e. doing odd end jobs) for your parents or guardians and/or your older siblings? If all else fails, when I was a kid--and I still am, at heart!--I was into the idea of writing a book (or two)! Well, I hope this helps, somehow.
On writing a book - and not going through the headache of getting a literary agent, publisher, editors, etc. - go investigate what Amazon is doing for novel and screenplay writers - they're taking stories through full development - and the royalties and other financing is clearly spelled out - this is scaring Hollywood and publishing houses who owned the means of production and publication - until now - Amazon is the future.
