Be comfortable in your own skin.

“The moment will arrive when you are comfortable with who you are, and what you are– bald or old or fat or poor, successful or struggling- when you don't feel the need to apologize for anything or to deny anything. To be comfortable in your own skin is the beginning of strength.” 

― Charles B. Handy

Tips :

Don't bond with people over body-bashing issues. Hanging out with these people causes you to feel even worse about yourself.

Stay around your true friends, they are the ones that love you just the way you are and think you're beautiful.

Keep a positive attitude! If you have a negative outlook on the world then you will have a negative outlook on yourself.

Pamper yourself! Go to a spa! They are professionals and can treat whatever you need treatment for.
