Journaling is a great idea in recovery because not only does it help us become attuned to our feelings, it also helps us a lot in planning for the future.
Journaling helps us make better decisions
Our mind is like a salad, it is being swarmed by a hundred different emotions and thoughts at any point. So trying to make sense out of our feelings is difficult. The act of writing (or typing) our thoughts and feelings will force us to clear the clutter and focus on the emotions that matter. It'll then be easier to identify the cause of the emotion and also to prioritize our actions moving forward. This makes it a vary useful tool when dealing with strong emotions. Make this a habit. When you have a strong urge or craving, log it before you act on it. It'll help put things in perspective.
Journaling helps us see trends
When you consistently record your thoughts and emotions, you will begin to see trends. This will allow you to understand how situations trigger your emotions (and hence your decisions) and consequently lead to actions. Once we understand the triggers, we can take steps to avoid and cope with them.
Set aside a time every day to log your thoughts and feelings. When you are journaling, try to express your feelings in words – it need not be pretty nor does it need to sound poetic. This is your own space. It can be difficult to begin with, but you’ll notice that the mere act of logging your feelings can help you think more clearly. This makes it a very useful skill for when you have strong emotions.
