Becoming more introverted in your late teenage years after being an extrovert up to age 16 is a relatively common experience for many people. Several factors could contribute to this shift in personality:
Hormonal Changes: During adolescence, there are significant hormonal changes in the body, including increased levels of testosterone and estrogen. These hormonal changes can impact your emotions, social behaviors, and overall outlook on life.
Social Dynamics: As you grow older, your social environment and peer group may change. You might encounter different social pressures, norms, and expectations that influence how you interact with others. This can lead to a reevaluation of your social preferences.
Personal Development: Adolescence is a time of self-discovery and personal growth. You might be exploring your identity, interests, and values, which can sometimes lead to introspection and a focus on internal thoughts and feelings.
Life Experiences: Specific life events or experiences could influence your personality. Negative experiences like bullying, rejection, or loss may make someone more reserved and less likely to engage in social situations.
Social Anxiety: Some individuals develop social anxiety as they get older, which can cause them to withdraw from social interactions and become more introverted.
Energy Levels: As an extrovert, socializing might have been a source of energy and excitement for you. However, as you get older, you might find that social interactions drain your energy, making you prefer spending time alone to recharge.
Cultural Factors: Cultural or societal norms can also play a role. In some cultures, there might be an expectation for young people to be more outgoing, but as they mature, there may be a shift towards valuing qualities like introspection and independence.
Remember, personality is not fixed, and it can evolve and change over time due to various influences. It's essential to understand that introversion is a natural personality trait and has its strengths and benefits. There's nothing wrong with being introverted, just as there's nothing wrong with being extroverted. Embrace your true self and focus on what makes you comfortable and happy. If you find that your introversion is causing significant distress or interfering with your daily life, consider seeking support from a mental health professional who can help you navigate your feelings and experiences.
