Will someone please help me?

Rather than focusing on the surface issues, think about the reasons -- and purpose -- behind what you do and why you choose to do it (with God's help). For example, it's stupid for your Baptist and Non-D friends to fight about which worship style is best: It's worshiping God at all that's important, not the style in which you do it. Same goes for your life and decisions. Simply pray for guidance, like "God, you know that I really love music and feel that you want me to go in that direction. If I'm right, please keep that idea in my head and support me as I try and go for it. And if I try it and fail, please reveal to me the lesson that you want me to learn." Finally, remember that at just 15 you're not expected to have strong opinions or know all of the answers; I'm far older and don't have opinions on everything. But I know who loves me and who I serve with my life (God). Good luck, as you sound like a really smart and honest kid.
