Eliminate negative self talk. Instead of hating on your body or picking apart what you don't like about your appearance, switch to loving accepting yourself the way you are.
Start by taking notice of all the talk inside your head. If you're bringing yourself down or constantly judging yourself, go to a mirror and speak to your reflection with loving words and affirmations, even if you don't fully believe them right now, say them. Keep doing this everyday until you do start believing in them.
Catch yourself every time your mind wanders off into a zone of disrespectful self talk.
Remind yourself that you are already enough as you are, and are already beautiful in your body.
There is no need to change yourself to fit into other people's standards of beauty, this goes for covering your face in harmful makeup everyday, or wearing clothes you don't actually feel comfortable in so you can be fashionably popular, for example. It's just a waste of time, money and your energy. It will only cover up your unhappiness and insecurities, causing them to pop up in harmful ways.
Remember that no one is perfect, and no one will ever be, so stop comparing yourself to an ideal version of a person who doesn't exist.
Allow yourself to see your real beauty. Give yourself permission to love the rawest version of yourself. Uncover the masks that hide who you really are.
Work on shifting the body image battle that is going on internally, into love and appreciation for your body.
Your body is a temple, so worship it.
Nurture it. Honour it.
Remember how to love it.
