You need to start being honest with yourself. Why do you feel bad about yourself?
An introvert is something who acknowledges he or she grows best alone, but sees the importance in being with other people too.
It sounds like you aren’t very sure about what you really want.
Just chill. Go out and have some fun with people you meet. Learn to get out of your comfort zone and talk to people. It’s scary at first, but you’ll get better.
