Darlene Egelhoff admits her estrangement from her reality TV star daughter was more painful than she could ever imagine, and she's even been prescribed sleeping pills to help cope with the turmoil.
In an upcoming episode of The Hills, Darlene tells Heidi's sister Holly: "I haven't slept in months. I had to go get a prescription for sleeping pills just to be able to go to sleep at night to the point that I didn't even know how I would even make it another day. I've been mourning the loss of a child and, yeah, it hurts. It hurts more than I thought it could hurt."
Heidi and her mother have had a turbulent few years, as the 23-year-old starlet underwent multiple plastic surgery operations and married long-term boyfriend Spencer Pratt against Darlene's wishes.
When Heidi revealed her transformation -- which included brow lifts, ear-pinnings and a chin reduction -- to her mother during a previous episode of the show, Darlene's reaction was one of the "worst" times in her life.
She previously said: "It was one of the worst experiences I've ever had in my life. She tore my heart out on national television. She is just trying to create drama in my life."
On another occasion, Heidi called the police when Darlene turned up unannounced at her house.
The blonde starlet filed for divorce from her spouse on June 8 after just 20 months, citing "irreconcilable differences".
