Oh gosh I'm sorry you're going through this lol
You did figure the solution out as intended. You just have to enter the Misty Woods and follow the directions given in the poem (2 directions per line, 12 in total).

Are you sure you didn't get anything wrong? Or maybe you're counting entering the first area as the first "north"?
I just crossed the area 2 times again to be sure, and it works fine.
