This is a real problem. You need to know that YOU ARE LOVED. There is only one of you in this world, that's why you matter. You are you and nothing can change or get rid of that. Always remember that. Stars can't shine without darkness. Sometimes you only fall into the dark so that you can see the light. People can't glow if they say they can't. You aren’t alone. This is a big world full with many people, some more big or strong that you but you've got to get back up on your feet, no matter what.
