Love vs Fear

My lips are sealed when i have just that perfect moment to talk to you. My feet are nailed to the ground when you walk by. My eyes smile when you, look into them. My heart stops,when you're not there. What i'm trying to say is, i like you. I feel like a breeze in your world, you know i'm there but you pay no attention. I should tell you my feelings, but i'm not confident. We come from the same world, but yet so different. I just don't know what to do. Is it rejection i fear? Can i really commit to a relationship, after being bruised very traumatically? What ever it is, i intend on erasing it out of my life for good! I don't want that one someone to come into my life, and never being that light in their day. You maybe just a high school crush, but i feel like you might help me to get over these fears. How can that be though? That's an answer i'm willing to find out soon.
