Delilah, 19, suffered her first anxiety attack at the age of 11, her mom Lisa Rinna revealed on Tuesday’s episode of The Real Housewives of Beverly Hills. “She had step throat and three days later she said to me, ‘I’m not getting on the bus to go to school.’ We had to have a doctor come to the house.

Rinna praised her “fearless” younger daughter’s bravery tweeting, “I am a very proud momma … you have touched so many! RHOBH airs Tuesdays at 9 p.m. ET on Bravo.
