I AM DEEP IN THE FRIEND ZONE! HELP!?

Okay so I am a sopre in High School, and there is this girl that is in my English cl, and I really like her. We have many of the same likes, but not too much where we are like exact replicas, but anyways that's besides the point. So this girl that I like, I have asked her out twice through text messages and have given her presents(On Christmas and Valentines Day). She has accepted the gifts and has loved them, unfortunately though, she only sees me as a friend, but I see our future together and it looks so promising, so I want to be much more than friends. Unfortunately, through the tone of her texts, she barely ever gives details, she just says stuff like alright and ditto, stuff like that, but trust me I don't smother her with love, plus sometimes it takes a while for her to text back, it basically indicates that she just wants to be friends. So all in all, I feel as though I had put myself deep, deep, deep into the friend zone with this girl, and probably screwed myself in the process. So please anyone out there on yahoo answers, please give me your wisdom! I really need help, I do not want to lose this girl, I want her as a girlfriend, but without forcing her to be so! Please help me in any way possible!
