Worried / confused that S + V

1) I am worried that she does not like me.

2) I am confused that she likes me.

I have heard that "be worried that S +V" is correct and natural, but "be confused that S + V" is not correct, but used by people. Do you agree with this? Thank you so much as usual and have a good day.

P.S All of a sudden, I am curious to know if "be used among people" is possible and it has the same meaning as "be used by people"? Thank you so much as usual.

I don't find "confused + that" very natural in the first place.

I was confused by the fact that she likes me.
I was confused by her liking me.

Thank you so much and could I ask one more? Then, how about "to be confused because S + V"?
