Frost, you think your range is confusing.
I've gone from being a bass (at age twelve) to being a high tenor by the age of twenty. At twenty-two I can consistently get a top C now with the right technique. I'm not particularly qualified to answer your question, but one word of advice to you is to not strain your voice. If you feel your vocal chords starting to ache or you start to lose your voice - stop there and then. I have got a Classical singing background, but I'm not a technician so it's probably best to seek advice from an actual professional!
