What happens next?
Well... First of all, in that explosion, some little pieces have been inserted in at least one of your friends, that one who stood there beside you, who tried to cheer you up and to understand you. You won't notice. You are so focused on yourself you just can't think about others.
Secondly, you feel even more lonely. You exploded, yes. But you didn't say anything about your problem, you keep it to yourself and you still expect for it to be solved. Sorry, honey, that's not how things and life goes.
You see, I'm still here, in case you want to talk about it. I've always been. You can take the hand I'm giving you or you can leave it. But stop fucking complaining about how unfair life is. You are right, it is. No one said it was going to be easy. But you have friends. At least, for now. Keep having that thick and awful wall in your heart and you will lose them.
I'm hurt too, I have my problems too, I am a human being too. We're not that different and you are not that difficult to help. So let yourself be helped.
