Hi Fascination,
That's up to you to decide.
I said 'No more' to myself many times before I actually made it stick. And, each time I relapsed things got worse and worse. And, I felt worse and it was harder to say 'No'. It's a horrible vicious cycle.
Please don't believe that at age 24 or 25 that you have made the wrong career choice. You can always change direction. And, if you are so passionate about dancing, why not think about pursuing that, and becoming a dance teacher. Follow your passion!
