Please help me !!! I need to make an important me make a decision

So I’m 14 years old and I really would like to start dancing, preferably hip hop. I’ve been doing karate for a year and a half and I would still like to continue while dancing. I’ve talked to my parents thinking that they would let me do both but they have said that I have to choose between one or the other.

I really enjoy karate and I would find it hard to quit. My belt is green white stripe. At karate recently won a trophy and two gold medals and one silver.

I’ve always wanted to dance but never signed up and I decided that this year I would. It looks really fun and enjoyable and concerts seem really cool. All my friends do dancing so I feel that I would be left out if I didn’t

Please help me make a decision ( I have to tell them my decision in two days )
