Hi there Rebeca! Welcome to TH! My name's Dez. I see that the guitar, piano, dancing, and swimming. Those are some great interests. How did you get into them, and was it difficult to learn them? I also see that you have made your first post on our forums. I even gave you a bit of an answer just now. I hope that you are finding everything okay! These links may help you out if you're not:
