Sorry you're going through a rough time with depression and doubts, etc. We ALL do! Whatever you feel might be hurting you right now, please - don't ever let it overwhelm you, and don't let it control you. You're too young still to let it take over your life. And if someone is telling you something that makes you doubt yourself, your value, your worth and importance as a human being, remember - they are doing it because they themselves are insecure about themselves, and only want to bring others down to their level. It's unhealthy and wrong. But if you're just having some internal doubts about something, it's ok. It's perfectly human. Whatever you may be going through, and hopefully it's over now, but know this - you're not alone. Look to the friends around you, and find the closest one or two, and let them know what's bothering you. They value you, and they know how valuable you are as a human being. Sometimes all it takes is someone else reminding us we that we are human, and we do hurt from time to time, and it's all a part of being human, and no matter what you are going through, you are valuable too. Stay healthy.
