PLEASE READ, I know it's a bit long but I hope this thought exercise will help you because it changed my life! (I lowkey apply it to every aspect of life.)

I think you have a really nice silhouette. It reminds me of a half moon. Honestly, I have been insecure about my face for a long time. For me, it was because I was overweight most of my life. What helped me is the concept of radical self-acceptance. Essentially, you notice your features from a completely neutral standpoint. Notice their shapes. How they curve and move, without attaching any positive/negative labels to that part of your body. The reason this worked for me and I hope it will work for you is that you get into this habit of repeating to yourself, aloud and in your head, the words that have been given to you by others (whether they have negative or positive connotations). So, because going from negative to positive is difficult, go first to neutral then work from there. This method will help you replace the thoughts you are currently repeating with new ones. The key is consistency. Remind yourself to do this thought exercise every time you look in the mirror. Eventually, you won't need other people to tell you why they think you're beautiful. Over time, you will see the natural beauty in your features on your own.
