Sometimes it's just hard when you know you have no one or no thing to blame. Even when I try to take the blaming route, I just end up back where I am knowing it is what it is. So trying to blame something is useless, and so is going "If I had only..." because you obviously didn't and it is what it is.
Sometimes it's just hard not knowing what you're going to do. Even when you try to think of strategies to help relieve the situation, and you find none of them really work... it's just hard sometimes to accept it is what it is.
But that's what it is. Try to remember that this too shall pass. That's all you can do sometimes.
