Hiya been there as an adult can't imagine how horrible this is for you as a teenager. First thing you need to do is go see you GP get some blood tests done and try and determine a cause. It shouldn't happen and their is probably a medical reason for it. Good luck 

I developed alopecia when I was 8 years old (summer of 2012) so I've had alopecia for 3 years nearly and it's not nice people calling you names like “bald headed freak is what I have been called on one occasion."

HI, im 22 and my hair started thinning when i was about 21, im gona give you some helpfull advice that will hopefully help you day to day that no one gave me smile. If you think your hair is falling out, start taking medication to help prevent it from getting worse AND DONT STOP TAKING IT. you might think that you don't need it and it will be too late by the time you start taking it again. also put it out of your mind you still have ton's of hair! Also. try not to play with it or put it in hair stressing hair dews as that can often times pull out your hair. The sooner you catch it, which 15 years  old is very early, the better you will be. i think if you start taking the medicine now whatever you decide (propecia ect.) you will have plenty of hair by the time your say 50. The medication does work, and it is more of a prevention that a cure you start taking it now and you will be okie! hope this helps.
