Whatever's happened to make you unhappy, let it go! It's in the past and none of that matters anymore. You've got a future ahead of you and only you can make it bright.
Accept that some people will hurt you. It happens to all of us. It's part of life and we have to learn to deal with it. It's those who care about us and only want what's best for us that matter.
Look around you and appreciate the things you DO have instead of focusing on those you don't. No matter how little you think you have, if you're able to sit at a computer and read this, then trust me, there are people not far from you who are far worse off than you are!
Keep a positive outlook regardless of what life throws at you and you'll stand a far better chance of dealing with your problems and enjoying the time you've been given to spend on earth.
