At the beginning of Eicha, we see Yerushalayim talking a lot about all the horrible things that have happened to her. She has been destroyed and abandoned and has no one to comfort her. All the people have left and they are in exile. All the buildings, palaces, and walls have been torn down. Everything is gone and everything is over.
        When something like this happens, the person who it is happening to is not able to see the situation clearly. Obviously Yerushalayim is completely heartbroken and will take some time to really understand what has happened. The one thing she does not see at the beginning is that the destruction is a result of her sins. She blames G-d for everything that has happened.
        One Shabbos last year Rabbi Feighenbaum gave a class all about blaming others. He said that when something happens that isn't right our first thought is always, this can not be MY fault, its because someone else did something. Mainly this is because we don't want to think we can do something wrong becuase we think we are better than other people. When we start thinking reasonably we might find that this could have had something to do with what we did and maybe we don't always do everything right.  
        At first, Yerushalayim is very overwhelmed and looks for the best person to blame. Soon she will realize that she is at fault and got herself in this situation. Of course its easier to blame someone else but that still won't fix the situation.
