Thinking

Thinking of someone sure is a torture. It is unbearable. It's like your brain was being stolen by that someone. You can't concentrate on anything you do. All you can do is just keep thinking of Him. Thinking about the things he said to you, thinking about the moments you spent together, thinking about everything related to Him. How can I stop it? Each time I want to concentrate on my assignment, I end up doing nothing but just surfing the net with my mind full of Him!! Why is this happening to me? Is this love? What if he doesn't feel the same? What will happen to me? Cry in pain? I don't want! I wish it's true love this time.....
