Detectives questioning me for something I have no idea about.

So this has been going on for about 3 months now. I am new to the area and in high school. Right before Christmas I got jumped by a local drug dealer thinking I broke into his car... Now ever since then he has told the police it was me and recently a lot of other robberies have happened in the area. Now keep in mind, my house was one of the houses and cars broken into. They stole money, and iPod, and a gun from my house. Everything was calm for about three weeks until yesterday. I got pulled out of class and detectives wanted me to go to the police station... So I went after school with my mom. When we got there the detective wanted to speak with me alone. He asked me a lot of rhetorical questions, but I answered all to the best of my knowledge. I'm really just wanting to know, next time I go down to the station or speak with the police about it, should I ask for my parents to be there and a lawyer? Everyone says to have a lawyer, but is it needed in this situation.
