This sounds like me:
In the sections that follow, I’ll briefly describe various characteristics of emotionally immature people.
They are rigid and single-minded. As long as there’s a clear path to follow, emotionally immature people can do very well, sometimes reaching high levels of success and prestige. But when it comes to relationships or emotional decisions, their immaturity becomes evident. They are either rigid or impulsive and try to cope with reality by narrowing it down to something manageable. Once they form an opinion, their minds are closed. There is one right answer, and they can become very defensive and humorless when people have other ideas.
They have low stress tolerance. Emotionally immature people don’t deal with stress well. Their responses are reactive and stereotyped. Instead of assessing the situation and anticipating the future, they use coping mechanisms that deny, distort, or replace reality. They have trouble admitting mistakes, and instead discount the facts and blame others. Regulating emotions is difficult for them, and they often overreact. Once they get upset, it’s hard for them to calm down, and they expect other people to soothe them by doing what they want. They often seek comfort in intoxicants or medication.
They do what feels best. Young children are ruled by feelings, whereas adults consider possible consequences. As we mature, we learn that what feels good isn’t always the best thing to do. Among emotionally immature people, however, the childhood instinct to do what feels good never really changes. They make decisions on the basis of what feels best in the moment and often follow the path of least resistance.
