Yea it does suck I think you're in need of some local finasteride. If you're 17 you haven't fully grown up so the pill isn't gonna do it for you, it'll screw you up. Start finasteride + minoxidil foam + dermaroller, it's the best combination in my opinion, nizoral shampoo doesn't screw my hair up so I use it. If you eventually start noticing it's not helping much add in RU58841 or stop finasteride and start dutasteride. I was just a little above NW2 on that age in denial because I had always had a high hairline, but now I've noticed it's a 2.5 getting to a NW3, slightly less worse than you so I decided to hop on it. Dude the amount of hair you can save and grow back is crazy if you use many things at once. People who you see complain on the internet generally only use 1 thing. Maybe on your case as it's a more violent type of hairloss you would just keep but not regrow but I'm 100% sure you can keep hair...
