I was looking for the opposite for "A load off your mind"

[Untaught88]

Hi,

I was looking for the opposite for "A load off your mind" or something which has the opposite meaning.

After a lot of struggle, I made this "That was a mental burden for me", is it correct?

 

[GoesStation]

A mental burden conveys the "load" part but not its direction. A load off your mind suggests that the burden was removed:

A: "I paid your library fines."
B: "Thanks! That's a load off my mind."

​ I can't think of a suitable opposite but I bet there is one.

'Weighs (heavily) on my mind', perhaps? It's not a commonly used phrase though.

 

[Raymott]

"A load on my mind". "Those unpaid bills were a load on my mind."

I wonder if that's a specific AusE phrase. I've never heard it in BrE.

I've heard "weight on one's shoulder(s)" a few times. This is what Ngram Viewer shows:
