I used to have the same issue as well with being envious of how cute other people are and being socially anxious. I’m only 2 years old than you, and I’ve mostly gotten over it and I’m sure you will as well with time.
I think what helps a lot here is working on your self confidence and self love. Chances are, you’re also really cute and awesome just like those people you mentioned above.
Yeah, I used to puppeteer a guy around so more people would like me as well, but I eventually accepted that some people are not going to like me no matter what. It’s really important to be kind to yourself. Be who you want to be, not who others expect you to be ♥️
