Hello,
I'm a girl, but I don't think I have a better advise for you compare to the others. All I can tell you...is that I totally understand you, as I was the same at 17 years old.
...nobody looked at me, I was invisible, and above all, very shy...redhead girl, with spots on every part of my face...you can imagine...
What i can tell you, is that it's not gonna last all your life, trust me! The key is to be patient (I know, it's hard). I had to wait for my 21 years old for my first kiss...now i'm 28, and I have more success that i ever dreamed of.
In french we have an expression that says, "the wheel is turning for everyone", i can tell you!
take care
