There is no point in worrying about past mistakes.
нет смысла переживать о прошлых ошибках. (net smysla perezhivat' o proshlykh oshibkakh.)
"We can’t change the past, so what’s done is done."
"мы не можем изменить прошлое, поэтому что сделано, то сделано." (my ne mozhem izmenit' proshloe, poetomu **chto sdelano, to sdelano**.)
A true friend tells you harsh truths to your face.
to fall deeply in love
raining very heavily
to have great influence or power over others
to end something; to finish a performance or event
to trust someone even though you may not have all the facts
