Good for you, doing something that makes you unique and special. Of course, IMHO, you shouldn't quit! Not many teens knit, but I did a little in the dark ages when I was your age, and my daughter, 13, is learning a little bit now. I think there are teens who post in this forum, too, and I hope they'll jump in and answer you, also.
There are patterns you might like right on this site - just click on the "free patterns" tab at the top of the page, then click on "household items" or "misc. (fun stuff)".
My son and my daughter both like the things I knit for them - you'll be able to make them for yourself!
