I am not sure how to answer this question: Are you taken care of?
I usually say - Yes, I am being taken care of.
You mean, for example, in a shop, when the person wants to know if you have either gotten what you need or that someone else is taking care of it?
I'm all set, thanks.
Yes, someone else is looking into my order.
Yes, I'm just waiting for the red-haired young lady/the rather tall young man/etc. to come back with my item.
Yes, there is someone taking care of me.
Yours is fine too.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
