It is more important that YOU believe in yourself and that you are special, which you definitely are. However, know that you have been a good, caring friend. As mentioned already, our value comes from what we think and not what others think of ourselves. When no one else is around, all we have is ourselves to be comfortable with. Believe in yourself and all that makes you, knowing that this makes you very unique and special. Your value lives within you, not others opinions and no matter what others think. Be true to yourself, trust in yourself, and find what makes you special to you.
