Can we ever use "regarding" with to worry, please?
-Don't worry about your new manager, it will be fine.
-Don't worry regarding your new manager, it will be fine.
(In this case, this person is afraid that her new manager isn't patient and open-minded)
"About" is probably more natural but is "regarding" accepted too?
Thanks a lot for your help.
I can't categorically say that "regarding" is totally ungrammatical but it is extremely unnatural and I wouldn't use it. In this context, "worry about" is the only natural way.
