Melissa Rivers took to Twitter to express her gratitude to all the fans who remembered her mom Joan Rivers on the second anniversary of her death.

“Thank you all for the love today,” Melissa wrote on Twitter on Sunday, Sept. 4, exactly two years after the comedian passed away. “Hard to believe it’s 2 yrs. Coop & I miss her every day.”

In a follow-up tweet, the 48-year-old “Fashion Police” host added that she thinks her mom would be so proud of her grandson. “One thing I know is my mom would be so proud of the young man Coop has become. That makes me smile even today xx,” Melissa wrote.

While undergoing a scheduled minor throat procedure at an outpatient clinic in Yorkville, Manhattan on Aug. 28, 2014, Joan experienced serious complications and stopped breathing. After she was resuscitated, she was transferred to a hospital and was put on life support. Seven days later, Joan died at Mount Sinai Hospital in New York, having never woken up from a medically induced coma. She was 81 years old.

According to CBS Local, the New York City Medical Examiner’s Office said that Joan died from brain damage caused by a lack of oxygen.

In November 2014, federal officials said that the Manhattan clinic committed a number of mistakes before and during Joan’s minor throat procedure. Federal officials said that the clinic failed to respond to Joan’s deteriorating vital signs and possibly administered an incorrect anesthetic dosage, among other medical-clinic irregularities.

In January 2015, Melissa filed a malpractice lawsuit against the clinic and doctors who performed surgery on her mom. This past May, the suit was settled for an undisclosed amount with the doctors accepting responsibility.

“I hope that this sparks conversation about care and policy at ambulatory surgical centers,” Melissa told Entertainment Tonight at the time. “If talking about what happened to my mother can help even one other family, it will have been worth it. As painful as it’s been to go through this, Cooper and I are grateful for the speedy resolution which gave us answers to so many of our unanswered questions.”
