Question

Answer

"I tried very hard to not show my emotions."

This sentence is not correct grammatically and semantically.

It is better to say: I tried very hard to hide my emotions.  OR I tried very hard not to show my emotions.

Some people would say “I tried very hard not to show my emotions.” Both are fine though
