I finally beat depression.. but now I don't know who I am? How can I find myself?

I am 13 years old. I've had depression for a long time, but I was diagnosed in November of 2010. Things started getting really bad, and I had to be put on 20mg of Prozac. I felt isolated in pain. The only thing I could do was lay there and cry, but once I started Prozac I couldn't even cry. It was miserable. I felt all of the pain inside. Everything I did, heard, or smelt made me sick. I hated all of it. I miraculously started to feel better about 3 months ago. Since then, I don't know who I am. I lost myself in the gruesome grieving that I was experiencing. I don't really care about anything but my boyfriend and myself, which is shameful. I don't know anything about myself. What is favorite kind of music? I don't know. What's my favorite store? I don't know. Favorite color? I dont know> Hobbies? Nothing but texting and making music. Favorite place? I don't know. It's all so... I don't know. And I know that may not make sense but it does to me. If I had to describe how I felt, it'd be I dont know. I need to find myself again. Please, any suggestions help.
