Undecided Question

I fear I may have a disease or mutation that makes me seem like a vamp. NO, I am not tryig to be one. Infact it annoys me when people say I look, act, or am like a vampire. This is what Im like:

-I was born on March 22, 1996 in Denver, CO
-I've had pale white skin since I was born and my upper and lower canines have been growing and becoming sharper since I got my permanent teeth. My lower canines just seem sharp, my upper canines where two centimeters long a few months ago and now their about two and half or three centimeters long.
-About two years ago, my skin started to seem like it was the color of the light Im under and I started to burn more severely than ever. I can be out in the sun and stuff, I just need to put on sun during the summer I need to put on sunscreen every hour.
-I dont like the sun much though, I actually like to be awake during the night and I do love the moon. I prefer the dark, it doesnt burn me and make me seem hot.
-My veins are visible and often pop out in every part of my body.
-My skin isnt tight so I dont think I have porphyria, but my skin and espicially my hand are almost always cold, but I sometimes get warm when Im around my best friend/girl I love with half of my heart, lol.
-The school counsler who has been counsling for fourteen years says I am mentaly mature than just about every guy in or below the tenth grade.
-I do look a few years older than I am.
-Im 5'3 and am very strong + fast. I often dont get sick, but I will get a cold once or twice during the summer.
-I am very smart but often wont pay attention in math simply because it bores me.
-I dont play sports, but still have loads of friends.
-I hissed at someone when they sneaked up on me without even thinking about it…
-I feel like I have lived through the 60s, 70s, 80s, and 90s.
-I like dark colors.
-Im very serious during school and "work", but get all fun loving, sociable, and humorous anywhere else at any time.
-I have gotten in a fight with fourteen guys and WON without even trying. I just wanted to get away, I get really pissy and protective over myself when I get cornered…
-Have I ever bitten anybody? No, but I have been getting an urge to bite my best friend Cassandra in the arm though I dont want anything bad to happen to her.
-In my school, everybody wears the same uniform colors white, blue, and tan, and same clothes, too, but once a month we have this thing called "Dress Down" day, where we pay a dollar to be able to dress as we please. During Dress Down day, I get stared at a lot but a few groups of people, and I ask my cousin Sam why they do that and he says "You look like a vampire, dude, it's creepy… No offense."
-I have brown eyes, but they will often turn light or dark brown, golden hazel and dark green.
-My doctor says Im going to stop growing at seven feet tall and she isnt very sure why my skin is the way it is.
-A lot of people say I am handsome, but others say my creepy looks make me look ugly.
-I dont think I usually act like a vampire, my friends, espicially Cassandra, say Im usually sociable, funny, smart, brave, athletic, creative, smart, sort of feminime, motherly, caring, and fearless excpet for my fear of Cassandra getting hurt or dieng. Im also very sweet towards Cassandra.
