teenbalding

Hey. I am a 17 year old teen who is experiencing this hairloss. Now i dont know the exact reason of it, maybe its stress due to exam, or no exercise, or crappy diet, whatever it is, I am too godamn young to be losing hair. Male Pattern Baldness run strong on my dad side of the family (my dad experience it when he was 25) while my mom side, there isn't much or no baldness at all.
Maybe I did get Male Pattern Baldness from my dad, and I wouldn't mind if it affected me in my late 20's and 30's, but i am not even 18 year old. Its just ridiculous.I want to solve this problem asap and I dont want it to be too late.
I remember as a kid, I had really thick black hair, people usually commented it on how beautiful I was and thought i would grow up to be a model, but now, my nose is broken and crooked. my skin got bad acne, my skin complexion is bad, and now i am losing hair. I am trying to be as optimistic as possible, but i don't know if I can carry on like this.
Guys, can you please help me with my hair, you guys have a lot of experience and a lot more knowledgeable than I am. I just dont wan't to be bald before reaching 20. Thank you
