Um, you know, some people don't have the true knowledge of Islam, so they would tend to call you names. That shouldn't depress you cuz Allah SWT will surely Reward you for all your efforts. Many do it for fun...but why should you care?! Just be Bindaas! lol
When I first started wearing the headscarf, in high school, my friends found it weird. They used to tell me to take it off. But of course it didn't last for long, they got used to it.
What one should remember is that no matter what you should be sincere and seek to please Allah SWT alone.
May Allah SWT make things easy for you. Ameen.
