The narrative in my head is sometimes a friend, optimistic, encouraging and helpful. At other times it's my worst enemy, driving my anxiety up and my mood down.
Your mood is a bit like the musical score to a movie.
Have you ever watched a scary movie with the sound muted? It can weaken the effect to comical proportions. The suspense and the drama is built up by the music. You're informed by the music whether current events and events about to occur will be happy or sad, scary or bland.
What might normally have seemed a mere trifle to be laughed off might appear to be a nightmare when your mood is black.
So how to change the score, to keep it bright more of the time?
For a person with a chemical imbalance, medication could be the answer. If you're at the mercy of your genetics and neurochemistry you may need some medical help to redress that balance and bring you out of a depression that sends your inner narrative down dark paths.
But genetically affected or not, good mental health and well being isn't as simple as swallowing a pill.
The mood of the story you tell yourself is affected by real events. By misperceptions about real events. By the coping mechanisms you use to escape real events.
Cognitive behavioural therapy, or CBT, can be a great tool to instigate change.
The essence of it is to break down the negative thought patterns that we all have, analyse them and ultimately change them for the better.
The main feature of analysis is to try to be unbiased, logical and reasoned. Similar to muting the sound on the scary movie, you need to look at the thoughts you're having outside of the situation they occurred in and consider:
1) What happened
2) What you thought in response
3) Whether those thoughts were helpful or unhelpful to you
4) If they were unhelpful to you, how you could have thought about the event more usefully
5) The outcome of thinking the way you did
6) The outcome of thinking the more useful way
As an example:
Suppose you were at the gym. An attractive girl walked passed you, glanced your way and for a moment her eyes flicked down to your belly. She walks on.
What did you think, how did it make you feel, what did you do as a result?
Let's walk through the six points for this example:
1) What happened
- a girl got your attention
- she noticed you
- she looked at your belly
2) What you thought in response
- I'm fat.
3) Whether those thoughts were helpful or unhelpful to you
- probably not :(
4) If they were unhelpful to you, what a more useful way of thinking could be
- she's hot, and she noticed me :)
- maybe could stand to lose a bit of weight there :(
- still she did look my way :)
5) What the outcome was of thinking the way you did
- made me feel unhappy
- made me go home and eat comfort food
- didn't help my waste line :)
6) What the outcome would have been thinking the more useful way
- stayed a bit more positive (or perhaps ambivalent) about the experience
- motivated me to do a few more crunches
The real trick with it is catching yourself thinking the negative thoughts. As you get better at it, you can see yourself about to have the negative thought and override it with the positive thought you worked out earlier.
