My dear,

You've done the great step..which is you acknowledge you feeling.

I used to worry what others may think about me.

One technic from "How to win friends and influence people" book by Dale Carnegie helped me.

I practice smiling in front of mirror. And I select the smile that I think it makes me most beautiful. Then I practice smiling like that more and more in front of the mirror.

When looking at mirror, smile . Look at your eyes in the mirror..Smile and say to yourself while looking at your eyes in the mirror "You're cute/pretty/beautiful".(select word you love to use)

Say this message/affirmation often. U will feel good about urself -> Your esteem grows

P.S. Next time you aware of your worry about other's thought. Just acknowledge it "Thanks for sharing." Then focus your thought to your magic words or affirmations like "I am cute/pretty/beautiful (more & more everyday)".

Here's the step-by-step self esteem help you can choose to do. And let your esteem shines.
