Kim Zolciak-Biermann had one serious case of the Mondays as she waved her loved ones goodbye for school and work.

The 38-year-old mother of six was a self-confessed “mess” as her son Kash turned four and started pre-kindergarten on the same day that five-year-old KJ headed to his first day of kindergarten and husband Kroy Biermann left to start training with his new NFL team, the Buffalo Bills.

While her sons looked super-cute in matching uniforms and ecstatic smiles, their mommy was meanwhile distraught.

“Im a mess today!! I swear I'll never get use to this,” she wrote on Instagram.

“My best friend, my everything left this morning to play for @buffalobills,” Zolciak continued in another post. “Although Kroy is so excited as I am (my parents grew up there, half my family still lives there) never mind the fact the fans are AWESOME, the team is AWESOME and my hubby is ecstatic ... It was hard to say good bye!”

Biermann previously played for the Atlanta Falcons, meaning he was based in his hometown. While she was sad to wave her husband off to work, the Real Housewives of Atlanta star was also proud of him and showed it with a follow-up post on Tuesday.

“Damnnnnn @kroybiermann Is killing me in his@buffalobills uniform!” she gushed, alongside two snaps of the athlete in his new gear.
