Hi, it is important to be comfortable with yourself. There are different kinds of people in this world, some are extroverts and some are introverts. If you are sentimental and introvert it is fine and there will be other people who are just like you. I understand that sometimes people are forced to blend into a certain kind of society that is different from their personality. In such a case you can train yourself to be resilient and still not change your personality. To help build resilience and confidence to face the outside world consult a psychologist and counseling sessions will help you.

Good day my Friend.  I can understand your concern. You are going through adjustment or coping issues. Be aware,  every individual is unique due to their upbringing, culture, society, lifestyle, priorities, environment, food habits, education, family values etc. So there is no one fit solutions for all.

You need a have  human touch  to ventilate your feeling and  emotions to identify the root cause of your problems . Then suitable solutions and therapies plan can be identified jointly. Appreciate if you can take the next by   talking to a counselor/psychologist. Go ahead and connect with any of us online for better understanding of your problems. Be positive.  You will be alright soon. Feel free to reach me online for further assistance and assessment of your physical and mental symptoms to recommend suitable solutions.

Hi... Being an introvert or sentimental person doesn't mean you are weak or you can't cope up with the world outside. There are good and bad people everywhere. In all walks of life, you will find people who are shrewd and selfish and you just need to identify them and be away from them. With little help of a Counsellor you can also learn the skill to deal with such specific people at work or elsewhere. Remember, you don't need to change yourself from within to adjust in this world. You just need to learn some skills to overcome such people or situations.

By your conscious effort and practising effective communication, you can learn to handle people..
