This is how a lot of women develop insecurity about their looks.

Someone gets ignored or treated poorly. They look around and see how beautiful women get treated well, so subconsciously they start to think they’re ignored or treated poorly because of how they look. And if only they looked better things would get better, and it just gets worse from there.

The solution is to restrict social media and influences in your life that place high value on looks. Surround yourself with people that value the whole person, that give compliments as much about looks as well as for your kindness or intelligence or what not. Look inward to find what you value about who you are that has nothing to do with looks and cultivate that part of your life. Increase your social media feed with body positivity messages that how your body feels and whether it’s working is more important that how it looks, and over time you’ll be less focused on looks.

Also google body dysmorphia as that might be what you’re struggling with.
