What do I feel?

When I think of her I feel light hearted...then when I think of not being with her, which somehow leads to me not being around her - I feel heavy. Why do I feel in such ways? What am I feeling? I don't want to give up, but if it's the end......will it make pain go away? Summer please come...summer please stay away. Laura where will you go? Who will you walk with hand-in-hand, smiling up at them as you share moments together? A lucky lucky guy.....
