After a nine-month social media detox, the "Real Housewives of Beverly Hills" alum returned to Instagram to share an update on her condition.
She wrote "After the loss of my mother i really struggled with depression followed by a lyme [disease] relapse."
The mother of supermodels Bella, Gigi and Anwar Hadid revealed that the heartbreak of losing her own mother had weakened her immune system.
"The emotional stress and grief strongly effected my immune system," she continued in her caption.
My phone addiction didn't help either, it started to take so much time away from being present in my life."
Hadid continued, "Texting is so much easier then picking up the phone and calling someone.
I realized that we are slowly starting to lose the art of communication and its creating a deep loneliness within us."
