Entertain. Make yourself happier by taking little joys of life. Make fun of whatever makes you feeling good.
I know it is difficult not to get upset and not to take things personally. The more you are a person living through every injustice the harder it is. Just give it a try and try to forget. Get through by something which you enjoy, something you lived yesterday and made you happy.
Always remember that it might by one of your last moments and it is a pity to spend it worrying.
All ends are good. And if it’s not good, it’s not over yet.
