SISTER Wives star Michelle Petty admitted she has been struggling after donating her kidney to a stranger in need.

Michelle gave her fans an update by sharing a post-surgery selfie in her hospital bed on Twitter, writing that “it’s been hard.”

She captioned the post: “Surgeon said I have a beautiful kidney and it is on it’s way to the recipient at UCLA.

“I am so appreciative of the kind words and well wishes that you all have taken the time to send.”

She continued to share updates in a Twitter thread.

Michelle wrote: “In the interest of being completely transparent through this, I have to say that the last few days have been HARD.

“But I had my follow up appt today and heard how well my recipient is doing & instantly made it all worth it.”

She admitted that she knew donating her kidney would be “hard” and prepared for the procedure by doing research so that she “knew what I was in for.”

Michelle added: “But going through it is different than reading about it. I don’t say this for sympathy or to be a martyr but if I am going to talk about my experience.”

While her body went from “feeling like a -1 in the span of a few hours” after the surgery, she said “knowing that somebody else is feeling Better than they have in years makes choking down a Jamba Juice with tears streaming down my face 100% worth it.”
