I'm sorry to hear that this is making you feel less confident... It is so hard to balance self love with the crippling weight of societal beauty expectations.
For me it helps the most to know that whatever we think of ourselves, strangers always see us different. I'm sure those who love you see 100 ways you are beautiful both physically and mentally that you don't. It's hard to see what makes each of us special with our own eyes sometimes.
We're also our worst critics, and maybe see these things more harshly than others do. A hug your way 🤗
