In addition to the right brain, another important function of emotional regulation comes from a small part of the brain called the amygdala. This section of the brain deals with not only emotions but also memory.
Only the most important or immediate information is supposed to stay in your short term memory. However, some traumatic or impactful memories can get “stuck” in short-term memory when they need to be processed into long-term memories.
This happens most commonly when an event is especially traumatic or painful or if it holds significant emotional value. These memories do not have to be huge traumatic events. Even seemingly “small” moments can hold significant emotional value and get stuck in this way.
I often refer to these events as “unprocessed memories.”
These unprocessed memories may cause emotional reactions more often because the information associated with these events is so readily available. The brain treats it as important, relevant information to the current situation, rather than something that happened long ago.
So, if you are experiencing sudden panic, feeling overwhelmed, or unable to control your emotions, it could be possible that these feelings could be traced back to an unprocessed memory still needing to be sorted out into your long term bank. Once this information is processed effectively, you will feel more in control of how you react emotionally, and the feelings will not be as intense. It should feel similar to something that happened a long time ago rather than something that happened recently.
