You shouldn't care about what you've been labelled as. What matters is who you really are. And that is something in your own hands. You are only a human and you will make mistakes. What matters is what you learn from it and what you do to make things better. If you've done something wrong to someone, that's okay. Go and apologize. Try to rekindle your friendship. Just try your best. Whether they come back or not depends on whether they are meant to be in your life or not. But at least their won't be any regrets that you didn't try hard enough. You are the sun who has its own light to shine with, you don't need anyone to bestow that upon you. It doesn't matter what others think. It does affect , I understand, but in the long run it doesn't matter. You know you are a better person right now than you were before. And that's what that matters. The people, fake friends or whosoever, you don't have to take revenge from them. Just accept that they don't matter now, now that you know who they really are, and ignore. You have so many more people to look forward to. So many reasons to wake up and smile everyday. So many qualities to be proud of. Take pride in who you are. Take care. Be Brave.
