My voice is really low, dramatic, and deep.......but I'm a girl?

its weird idk if i like it very much. i love singing and ive been in chorus all my life and i do plays and musicals but my voice is weird to me. i always record myself on camera to hear how i really sound, and its always like really drmatic and idk how to explain but its like almost like a really heavy voice. im only 15, and i have never heard any person my age that sounds like me. and idk if its a bad thing or a good thing but im not used to it so whenever i hear it its like woah! im a very low alto and 1 time i even sang tenor in a play but when i sing high it just sound a bit less heavy or dramatic
