The next time you feel as though you just have to talk to someone about something that's making you uncomfortable or unhappy, don't do it. You can learn to use that pressure to free yourself from all such feelings that want to push you around. Here's the explanation: finding relief is not the same as finding strength.
That disturbance within you, whatever its reactionary nature, isn't real. It's really nothing that just feels like you. That's why you mustn't do what it urges you to do, or you'll unconsciously lay claim to its weak and self-compromising nature.
From this moment forward, consciously challenge the right of any dark disturbance to direct your life. Stand your inner ground until its demands drain away. Negative states have no real life of their own, so consciously withdrawing your life from theirs is the same as commanding their dark presence to fade. Once the pressure is off, you can then choose to say something, or not, about the conflict that was in question because, at this point, you'll be in command of yourself and the situation, instead of being unconsciously commanded by it.
