I Don’t know what I’m doing with my life

So I’m 14 and I am literally not doing anything with my life. And I’m not saying like I never go out with my friends, I am not doing ANYTHING. I just go to school and sit up in my room eating snacks on my phone watching other people live their best life. And I am all for everyone living their best life and all but, why am I watching while they’re doing? I was a dancer but I had to stop bc my parents had to put both my sisters in college so I been gone for 2 years and I been begging my mom to go back and She’s just like “yeah I’ll call them.. yeah I’ll email” but I’ve been asking about it like everyday and she just said I have to give up on it bc it’s just too much money. I kinda just got depressed and was crying to myself in my room bc like if I can’t dance, what am I gonna do? Soccer? Lacrosse? Gymnastics? All I know is dance so if I can’t do that I Don’t know what I’ll do. And dancing was the only thing I was gonna have going for me, and now I Don’t even have that? What if I get fat or my health drops? I understand if it’s expensive and all the expenses that my parents have but, I needed that and she just snatched that hope right out from under me. And i Don’t even think She’s trying to put me back In competition dance. My brother is on tenteen(I know it’s not a real number) different sports teams but I can’t even be on one? I know my family loves me and they want the best for me but... So I’m just very down and I needed to vent and some advice:/
