Feels like you're a piece of Side-walk Chalk

What do you do when your friends' worlds are crashing down around them while you're still standing? How do you comfort a friend who's just cut themself when you have no idea what they're going through? How do you encourage someone while they're parent is saying things you never imagined a parent could say?I'm sheltered. I have no idea what to say to my friends! I end up repeating myself: "i'm sorry."I know sorry isn't goo enough. It doesn't help them any. Why did I have to get it so good? I'm the type of person who wouldn't have suffered too terribly if I struggled. Why does it seem like everyone around me is in pain and I feel fine. I want to be able to do something for them and I can't. Remember when you drew with chalk and would get one shape drawn and already the chalk was down to a stub? You could feel it turning to dust in your fingers as it ground against the cement. Life sucks like that sometimes. And the best you can do is make sure the picture that's being drawn is worth it. That it leaves a stain even after a rain tries to wash it away.
