Emotions go unacknowledged and unidentified all the time, although not unfelt. This poses a problem in the long term in that due to this lack of awareness, our internal emotional compass becomes unreliable, leading us to make mistakes (i.e. emotion based decisions), unnecessarily fail , and inadvertently slowly pull ourselves further from the Self (i.e. becoming confused about who we are, identity issues, etc).
Keeping track of emotions and dealing with them as they occur is important in preventing mental health and emotional issues that might arise throughout life.
