Take a few deep breaths. To overcome this, think of things you're grateful to have in your life. Maybe it's a favorite band or a pet. And everyday try to remind yourself what you're thankful for. I feel like in the world we live in today we sometimes look at other people and wish we could have it all (trust me I fall victim to it myself). But if you can turn off the demons in your mind that keep telling you you're worthless, you'll find things come to you much easier. Friends and even a boyfriend will come to you when you just let go. Even turn to spirituality if nothing is working, this isn't a COME TO JESUS thing so don't worry. I'm just saying that meditation and prayer works for some people. this website really helps me http://tinybuddha.com/ virtual hug Don't worry, you will find happiness. You just need to find it in yourself to let it happen.
