I'm 17, he's 18 - I don't think I just fancy him - I know people are gonna say there's no way I can love him if he doesn't like me back, but I've liked him to this extent for 7 months now, and I can't stop thinking about him. I get flushed whenever we speak, I can't sleep properly for thinking about him, and as said above I feel weak and dizzy when I see him unexpectedly. And I get butterflies when he smiles at me. It's a horrid feeling - I feel down and depressed if I don't see him in a day, and if I do see / speak to him, I always get so happy, and my friends can all tell a big change in my mood after we talk. I dunno how to explain it, he just makes me feel happy.
