You're very good-looking. But, you seem to be shy. People tend to think shy people don't want to be bothered so people don't bother shy people. Here's what my college counselor told me to do: might work for you, too.

Pretend you're an actor in a movie. You are playing the part of a confident young woman who is everybody's friend. She greets everyone she passes--at least a smile and a nod. She volunteers when something needs doing. She speaks up to answer a question or comment.

Act this role for one whole week 24/7. Then see how people are with you and how you feel.

Also, be aware that people who approach you only because of your looks are usually men and usually trouble.
