Hello Critique!!
I think since you have been a shy and reserved in nature, you find it hard to speak in front of more people or crowd..
Practice speaking in front of mirror.
Don't feel complex about
yourself, no one is best and wonderful as yourself, have that kind of thought in your mind.. don't panic or feel shy, whatever you do, do it boldly.. whether it is right or wrong.
While you move with others feel that you are the queen.. always be the first to start the conversation with your friends or others. Don't wait for others to talk to you.
Follow these, you will surely see a difference in yourself.
Keep going..
All the best!!
