After a tragic year of loss, Silverman had an absolutely chilling brush with death last week, recounting the doctor's visit that turned into an ICU stay on her Facebook page on Wednesday.
"I was in the ICU all of last week and I am insanely lucky to be alive," the 45-year-old comedian shared. "Don't even know why I went to the doctor, it was just a sore throat. But I had a freak case of epiglottitis."
Epiglottitis is a life-threatening condition where the tissue surrounding the windpipe becomes inflamed, blocking air to the lungs.
"They couldn't put me fully to sleep for the recovery process because my blood pressure's too low," said Silverman as she continued describing her hospital stay. "I was drugged just enough to not feel the pain and have no idea what was happening or where I was. They had to have my hands restrained to keep me from pulling out my breathing tube."
"When I woke up 5 days later I didn't remember anything," she continued, before thanking her friends who stayed with her the whole time. "It makes me cry. Which hurts my throat. So stop."
In the gripping post, Silverman also grappled with reconciling her near-death experience to some close personal losses she's suffered of late.
"There's something that happens when three people you're so close to die within a year and then YOU almost die but don't," she reasoned. "It's a strange dichotomy between, 'Why me?' and the other, 'Why me?'"
While it's not clear who specifically Silverman is referring to, the Wreck-It Ralph star has dealt with the tragic loss of several friends and loved ones recently, including comedian Garry Shandling in March, former Parks and Recreation co-executive producer Harris Wittels, who died last year, and her mother, Beth Ann O'Hara, who died last August.
