If I Was Born Dauntless

I'm Beatrice but I like to be called Tris. I have 2 brothers, my twin Uriah, and my older brother Zeke. Our father died when we were about 8 and Zeke has been my father figure ever since even though he's only 2 years older. We were all born in Dauntless. Zeke's best friend Four transferred when Zeke chose to stay 2 years ago. Now it's mine and Uriah's turn to choose which faction to live in. For Uriah it should be easy he'll stay in dauntless. But for me unlike most people on my aptitude test I got three of the five factions. I am Divergent. My factions were Erudite Abnegation and Dauntless. I want to stay with my family and friends so I will most likely stay in Dauntless but it would be nice to start a whole new life. I don't know what to do...
