You
are the only person who is in charge of how you feel about
yourself.
Nobody else can possibly do that.
You get to decide if you believe you are beautiful or not,
and nobody can take it away from you.
If someone suggests that you aren't beautiful, you can
consider how sad it is that they have such a limited view of
beauty.
You can consider how unfortunate it is that they have such an
exaggerated sense of self-importance that they think you
should care about what they think.
You can also choose to realise that it has nothing at all do
to with your beauty and everything to do with their
limitations
