What could be causing my hair loss?

Ok, i really am in panic right now. I'm 17, female. My hair has been falling out a lot and i'm not sure why. I never dyed my hair and i didn't straighten or blow dry it either. Everytime i comb my hair, it comes out. If i keep combing, it'll keep coming out. This is really killing me. I've been really stress lately because my face has been breaking out for a year now. My confidence just went down tremendously. And now my hair falls too!! I have naturally thin hair and today one of my classmate out of blue just said like,


'; Hey how long have you suffered hair loss?';


I was like, '; I didn't!';


He said,'; Oh come on, your forehead is almost bald.';


I nearly cried but i didn't show it. I just walked away. I don't know why everything bad suddenly happens to me. My life was so good before.. But then acne came, and now hair loss too!! Pls help!!What could be causing my hair loss?
at the age of twelve i was starting to lose a lot of hair and i didnt even notice until one day a guy in my class goes';hey lilian! i think you have a bald spot at the back of your head!'; and i was like reaaaally? and it turns out i did, it was like just a bit bigger than an averarage bottle cap. so i went to a hair specialist it i was diagnosed with this hair loss disease, i need to put oitments on it and if that wasn't going to work, they would need to inject something in my bald spot. i was soo scared i refused to ever go see the lady again, thinking shed inject my head. im 15 now and the bald spots completly gone and ive never been better, bald spots can hit anywhere though and yours is apparently on your forehead which is rather very unlucky, but just get it checked out, good luck with everything, i seriously feel for you ! %26lt;3What could be causing my hair loss?
