Question for theatre veterans

Hi there. I am sixteen and live in a very small country town. I was unable to complete my school certificate (after 2 years of attempts) due to chronic illness. My illness is now being controlled and I am ready to get back to the real world. I am desperate to learn the art and discipline of acting. I am very serious about this, and all my life performing has been my passion. To learn to perform in theatre would be a dream come true, and this dream I am adamant I must pursue. However, the small town that I live in does not offer a theatre group, or acting classes. I would move to a larger town, but would face major financial problems, as being so young and without qualification, it could be highly difficult for me to earn a living. My question is, do you have any advice on where to begin? Please advise me of what steps I can take to make this dream a reality. Thankyou.
