Or maybe you should choose. When you say you want to be a dancer, do you mean professionally? It's a tough life, but it can be done.
If you want to be a professional dancer, maybe you should consider changing your major to dance (in the US; other places, you may need to go to a dance academy).
If being a dancer means you want to always dance for your own pleasure (but not necessarily earn money at it), then keep dancing but focus on your studies. You have the rest of your life to dance and you want to get a good job so you can afford all those dance lessons, shoes, clothes, etc.!
