"Surgery is never fun," she captioned a snapshot of herself in a hospital bed on Friday, March 4. "The third day for me is always the worst day for me. Yesterday (my 3 day) was quite aggressive. All I can remember is I threw up all day—— I was so sick, I threw up and cried, threw up and cried."
She explained that her fiancé Ben Youcef "didn't know what to do" and instead, spent the day "rubbing my back, holding my hair back when I was bent over the sink" and trying to make sure she had food and water.
Later in the day, the couple decided the reaction she was having was far too severe and rushed her to the ER, only to discover she had "some kind of infection" that caused her kidneys to work at only 30%.
Lee added they are still unsure exactly what happened, and they are awaiting her blood work results to confirm.
"Surgeries are so brutal but I’m still glad I did it," she continued in the lengthy caption. Lee previously elected to have the surgery seven years after her battle with breast cancer which resulted in a double mastectomy. "Ben stayed with me as long as he could, he was so patient."
She also mentioned her intense "wanderlust" and how Youcef helped distract her from her health woes by researching "beautiful villages that we could drive to this summer" to take her mind off of things. "No amount of time on this beautiful planet will be long enough."
"I hope your days are easy and healthy and then full of adventure," she wrote as her post drew to its conclusion. "Have a good day! Look around you and Enjoy It…Life is Beautiful! With love - Sandra".
Lee and Youcef first sparked rumors they were dating — and engaged — last August after they were spotted cuddling and kissing in the streets of Paris while the Semi Home-Made Cooking author rocked a sparkling diamond engagement ring.
They have yet to announce a wedding date.
