Tbh this seems like a deeper issue. Have you ever tried speaking to yourself? Like I know this sounds weird but if you stop looking externally and start looking internally and really understanding yourself you’ll start seeing a version of yourself that goes deeper than just what you look on the outside. Yeah I can give u tips and tricks on how to look good but none of that will do anything without you really figuring out what this insecurity comes from. You will never be able to stop comparing yourself to others and truly love yourself without understanding who you are.
Dive into EVERYTHING that interests you!! Go on a self discovery journey, talk to yourself, internalize, meditate, be passionate, be a good listener, be kind, be genuine, maybe journal and list the things you are grateful about, the things you are good at etc, DONT obsess over appearance it will ruin your soul!!
I never really cared but these days I just keep getting insecure about my appearance and comparing myself to others. It's like every girl around me if beautiful asf and have good personalities and then there's just me ugly and boring. The more I look at myself the more it grows and idk, I try my best to ignore it but sometimes I just randomly think of it and get more insecure... How to make it stop?
