How do I stop feeling unattractive?

Try doing some mirror work! Start by standing in front of a mirror and just looking at yourself. You may notice that a lot of critical thoughts come up as your mind focuses on picking your appearance apart. It's important to remember that these initial critical thoughts are not the truth—they are just the voice of your inner critic speaking. The more you ignore the inner critic and focus on finding things to appreciate about yourself, the more confident you will be. Actively practice looking in the mirror and finding things to appreciate instead of things to criticize. If you do this over time, you'll start to get in the habit of appreciating how you look instead of criticizing yourself.
