I used to be very introverted and didn't talk to everyone. In recent months, I like to laugh and talk. My mother can't accept me being like this and says I'm crazy. You said change.

Nothing is good, see if you like it. Just be yourself. Don't give yourself too much pressure. Your mother may feel uncomfortable about your sudden change. It'll be all right in a minute. However, optimistic and cheerful people are generally more popular than introverts. Don't worry, let it be.
