Not to be confused with "get over it," to "get over" is 70's African American slang for getting through the hard times. The opposite of "going under," when a person gets over they manage not to fall apart when things are bad.
In a more simple use, "getting over" occasionally was used to mean dealing with bills/taxes and getting out of the red.
"We gotta get over before we go under." James Brown
"United we can get over, and yet we're still apart." Willie Hutch
Sentence: "There's nothing I won't do if it means getting over for another day."
