I think it means you are not feeling ur self idk I just guess:]

Not feeling comfortable or confident in yourself and feeling judge and the need to hide

Self

Not believing in your seld

For example, if you have self doubt that means that you might be insecure about yourself. I hope this helps. And if you think things like this stop thinking them because everyone is beautiful in their own way. ❤️

at least if you speak Spanish you will know!!!

Sentirse/a de su aspecto fisico!!!

then how you typing in English?
