To get over any girl follow the following route.

  1. Start physical exercise. Physical exercise has known to work in your favor. It clears chemicals from your mind and make you feel rejuvenated.
  2. Vent out your inner feelings. Write them down or share with a close friend.
  3. Work on your looks. When we focus on ourselves we tend to feel great.
  4. Stop contacting to that girl (or boy). Slowly back off. More you contact , more obsessive you become.
