I have a gut feeling that you're being told these things from jealousy. I think you probably are pretty and beautiful, but some people resent you for it and try everything to stop you feeling good about it.
I know you;re not useless, or brainless. What you have to do is take hold of the situation, and really, truly think hard about what you think about yourself. All the things you;re good at, all the features you think are pretty, how nice you are, how well you treat people, all the things that make up a positive human being. Think about them, and remind yourself of them. When people do their best to discourage you, remind yourself then of why they are, and remind yourself of what you really are.
In time you'll see yourself the way you are.
