Carol:

Thanks for the honest question:

Nehemiah 8:1 has people gather at the Water Gate in a very public way. Nehemiah 9, their repentance is very public.

Jeremiah stood at the gate of the temple, one of the most public of places in the nation (Jer 7).

Finally, imagine writing books of prophets calling for repentance and naming sins of God's people and placing them in a sacred text for anyone to read to see God's standards?

David wrote Psalms of repentance that we sung and recorded. 

Do these help to answer the biblical standard that repentance is something that is not to fear being publicly declared?
