You have to start looking at yourself in a positive way, people around you are no one to judge you.
Try to be confident in front of them that you have surpassed that level
Where you used to get affected by them.
Every metal is precious. There are lot of treatment and make up products to change ones look. So understand that look doesn't matter if you really know to accept yourself. Be confident of yourself:)
bullies are people who decide to let out all of their personal frustrations on people and are feeling insecure about it as they lash out on you. Don't let them get you down and instead, love yourself for who you are! (It's easier said than done, so try to start with baby steps, one at a time). Honestly, don't mind their commentary. I don't even know you yet I believe that you can get through this! :)
