Longing for something in the hope of getting it one day is understandable. But when this longing becomes a source of pain, then suffering is not healthy. It is difficult to move on but it is the only way to live peacefully and more productively. Focus on yourself, look at doing things which will help you grow as a person. Start some exercise. Make conscious effort to eat healthy. Go out of the way to groom yourself. Start doing something that makes you feel good. Distract yourself by involving yourself in productive activities. You ll realise that the world is full of possibilities.
