Kim Zolciak's friends -- at least some of them -- don't want anything to do with her ... saying they're embarrassed by her behavior over her public divorce from Kroy Biermann.
Sources familiar with the situation tell TMZ ... the couple's relationship saga is a sad situation for their four minor children ... expressing concern they're forced to witness the drama play out at home and also relive it publicly through media coverage.
As a result, some of Kim's pals have distanced themselves from her over the last couple months.
