Every ending is just a new beginning. Every dark tunnel has a light spot at its end. Its just that we're too busy drowning in the darkness and in our sadness that we don't notice the light, we don't notice the new opened doors and chances for us. Whatever is gone had left an empty space for something else and hopefully better to occupy it. We just keep dwelling on the emptiness it left and the blank space ; However that emptiness is meant for something more fitting to fill it. I think what you should do it open your eyes a bit wider, Look again and look deeply. Let your heart be,Don't put barriers or limits just because you're hurt. Don't stop yourself from doing what you feel. Let go. And let be.
