Don’t think like that, like you can’t go on, or it won’t be much longer, or it’s not true, or the end is near, or nothing matters, or anything else that might be true, but doesn’t help you by its truth.

Because you can be illogically happy or illogically sad – those are the only options, humans are not smart enough for anything else. So push out of your mind any thought that might be true but isn’t useful.
