How can I make them see me differently?

Changing anyone's opinion on you involves changing you into who someone else wants you to be, and that person is not who you are.

How other people see you isn't necessarily as important as how you see yourself. If the opinion of others is making you feel bad about yourself, the opinions may not be worth listening to, no matter where they are coming from. In your own way, you are special, and beautiful, and it does take a lot to be able to find that within yourself. But once you find the positive things that YOU love about you, people will start to notice your confidence and your happiness. And that is the best way for people to see you differently.

Just accept the ways in which you think you will become different in their eyes or can focus on your success and goals

It would better to slowly do things you normally would instead of making a 360 degrees change. If you want to be seen in a different light then stop doing the opposite. Think before you act.

Just be the change that you want to see in yourself. You cannot make others see you differently but you can change how you see yourself.

You could focus on your positive attributes, helping them see what you want highlighted within yourself- positives, positives, positives.
