I’m in a cult?

I’m currently at a close family friend’s we’d who I have not seen since I was a child, this past Friday me and my mother( not Catholic) were joking around at breakfast if eggs count as meat (completely lighthearted and not thinking), when the close family friend said: “I’m so happy I’m not in a cult and can eat what I want” and a lot of other hurtful things about Catholics. I told her I was Catholic and I would appreciate if she’d stop. She did not. I ran out of the room to cry and my tried as she could to defend me. I know why we fast and abstain from meat and the practice has strengthened my prayer life and grown my appreciation for Christs sacrifice. But it hurt, it’s the first time since converting I’ve been approached so negatively about it.

But also it’s planted seeds of doubt, only because I’m very very interested in cults, have books about them, watch documentaries, and have just always been interested in the subject. Am I in a cult? I can’t possibly see how or why but I know it’s a common accusation?
