The Dangers of Neglecting Emotions
As a highly emotional person, I end up acknowledging my emotions and letting them govern me more than required. However, I have seen many people around me who can't identify the emotions they're experiencing and try their best to avoid them. I never saw the benefit in doing this so that's probably why I've not neglected my emotions. That's why I had to do a bit of research before writing anything about this topic.
I found information about childhood emotional neglect and how people who neglect their emotions often had emotionally unavailable parents and parents who discouraged any kind of negative emotional expression. This is what mainly causes people to neglect their emotions. Many adults who have bad relationships with their children or spouses are often found to have very low emotional intelligence and self-awareness. This means that they don't often know why they behave the way they do or how their emotions affect them, in fact, they can't properly identify what kind of emotion they are feeling whether it's anger, jealousy, sadness, joy, etc. They're very disconnected from themselves which in turn leads to them being disconnected from people around them like their friends, partners, family, and children. This means they can't form deep or personal connections with them. It's especially problematic in romantic relationships as the person fails to understand and meet their partner's emotional needs. They are unable to identify when their partner is struggling or needs their support. This strains their relationship and both partners end up unhappy.
This isn't something that can't be fixed though. Many people go through therapy to learn to be more in touch with their emotions and be more emotionally available to others around them. They feel less embarrassed about showing their emotions and the trauma they've gone through with their parents starts to heal. I've heard from multiple people that they'd prefer to feel nothing and have their emotions numbed but that doesn't lead you anywhere in the long run. Sure in that moment you don't have to deal with any of the emotions that make you feel terrible but later on, you're going to have many problems socially and you'll never truly know yourself.
