I need dance advice and support!

So I danced from when I was four until I was twelve. I competed for two years around New England and went to nationals in New Jersey and South Carolina. My dancing included tap, jazz, ballet, lyrical/modern, acro, some hip hop and some gymnastics. I had to quit though because we couldn't afford it anymore, and if you dance at a good studio or if you have ever competed, you know how expensive it can be. I've always missed it and I am missing it more and more recently. I yearn to go back to how flexible I used to be and how I could just express my self through it. Good news is coming though because my boyfriend's mom owns a gymnastics place and for the past couple of weeks every wednesday (day during the week I don't work)I've been able to work out with her team for free. This has certainly been a blessing and I can already feel everything coming back to me. It just feels amazing to be able to get closer to what I love doing. I absolutely love to sing too and tell me I have crazy dreams but I would absolutely LOVE to be on Broadway someday. That would be an amazing accomplishment to have in my life. I'm 17 soon to be 18 in September and I know most people start working towards these kinds of things when they are younger, which I have but I got lost along the way, but some advice would be great from someone who gets what I'm rambling on about and has been there and done that. Anything is much appreciated. Thanks! =]
