I understand completely how you feel. Although, I don’t feel my best friend is more attractive than I am, she has this amazing personality. She stands out and I always feel like nothing. It’s hard for me to make friends, while for her, she can make at least 10 friends in one day. So, yeah, I totally get it. There is only one thing you can do however and that is to fix the insecurities you have about yourself. To have more self-confidence and more self-value. Because there is nothing you can do to make her less attractive or less appealing personality wise nor can you make other people like you more. It all has to start within you. Change how you feel about things. You have to go deeper within yourself and figure out what’s wrong.
