Kate Gosselinis still reeling from the physical and emotional effects of a frightening injury sustained while competing on FOX’s gruelingSpecial Forces: World’s Toughest Test.
“I’m still so pissed. I’m so angry,” Gosselin tells PEOPLE. “I was out and it was done before it even started.”
Duringepisode 1 of the boot camp reality series, theKate Plus 8star, 47, and her costars were tasked with falling backward out of a helicopter into open water.
“Water and height are two of my absolute fears,” she says. “Yet at some point making that turn in that helicopter, I remember thinking, “I’m sorry, you don’t have a choice here. I know you’re scared to death, you’re doing it. Do it and get it over with.”
Gosselin did — and immediately knew something was wrong.

“I landed right on my neck and I screamed when I landed because it was absolute ridiculous pain,” she recalls. “Then at some point I started feeling nauseous and I was dry heaving over the edge into the water.”
Gosselin, who has a medical background, begrudgingly decided to seek help.
“I knew, being a nurse, that I had to go get checked out and make sure there was no lifelong injury there,” she says. “My neck still bothers me sometimes. It is muscle. I do tend to carry stress in my neck and shoulders. So I do think that that probably was a factor in it, then hitting it smack dab on the water.”
The injury forced the mom of twins and sextuplets out of the competition.
“It took me so long to get over that,” she says. “I still don’t think I am. Because I really wanted to challenge myself.”
