How can I talk to this girl without her thinking I'm a loser?

Before I go to school in the mornings, I get erflies really badly because I know I'm going to see her today, beautiful as always. I always wonder how she's going to look, what she's done with her hair, how she's feeling, and yeah. Every single song I hear reminds me of her - soft, loud, emotional, funny. Oftentimes in my imagination I fantasize about coming to her rescue, or holding her in my arms and making her feel loved. I wuv her shimmerig blue eyes, her long wavy hair... awe, just thinking about it makes me want to go cuddle with my blanket and pretend it's her, pressing my cheeks into an imaginary face, snuggling up and falling asleep. When I go for walks, I often go alone and have my hand out as if I'm holding somebody else's hand (and I wish it were hers). But I can't talk to her, I just can't. She'll see right through my eyes and think bad things about me, then it'll scar me when I hear her laughing to her friends. But why should I be so afraid? She's such a kind, gentle girl - like she'll ever make fun of me. Actually, no, I'm an exception. But how can I talk to her, you know, without stammering, blushing, trembling, or forgetting what I was going to say?
