Well, my pinky is about 2 1/2 inches, and my other fingers are insanely small. I've had problems such as you since the get-go, but here I am almost 7 years later. I can't play certain chords such as the C minor open, but I can play it barred, so it's okay. :) Don't worry, some things will actually come to you better because of your small fingers. I can do a decent shred, not great, but better than some IMO. I've been told many times that I make guitar playing look easy, and its something that I really am proud of. So don't fret, just practice, you'll find that some things will come to you better than others. Good Luck!
