What can i do to not feel offended?

They're probably just doing it to get a reaction. If it really bothers you, then tell them to stop being ignorant and it's making you feel uncomfortable. The comment "Y'all think you can have it all" makes it sound like she is jealous. Some people think that people of other races get preferential treatment, or even people within their same race because of how they look. So even if you end up not saying anything to them, just try to keep that in mind and don't let them get to you.
