"I'm shattered," Abbey told HELLO! at Fashion for the Brave on Friday night. "We've been doing the Charleston this week which is a million miles an hour. Full on. But I'm really enjoying it and I just hope I don't find myself in the bottom two again.
"Being in the bottom two was horrendous," added 27-year-old Abbey. "It was horrible. Especially being there with Rachel [Riley], who is my really good friend on the show."
Dressed in a sheer, Union Jack-adorned dress, designed by her former Strictly co-star Julien Macdonald, Abbey told HELLO! "Everyone's made a really good bond with each other.
"There's no bitchiness, there's no competition. Everyone is genuinely rooting for each other and wants them to do well."
Having formed a successful dancing partnership with professional Aljaž Skorjanec, Abbey said that is was a "shock" to be second in the leader board and still face leaving the show.
"I've been second in the leader board pretty much the whole way through," she said. "So it was scary."
Abbey's success on the BBC1 hit show has meant compromising spending time with her footballer husband Peter Crouch and their daughter Sophia.
"The only downside to the show for me is being away from my daughter," said Abbey. "Im used to doing my jobs like a couple of photoshoots a month and a bit of presenting here and there, but the majority of my days are with the baby."
"So to have to put her in nursery all day," she added. "And for Pete to pick her up and it's dark when I get home and she's in bed - it's quite hard."
However Abbey reveals that despite being "less nervous giving birth than doing Strictly," it's all been worth it.
"I'm having the time of my life!" she says. "I almost feel guilty for loving it so much!"
The blonde beauty also suggested that her love for the show has been rubbing off on England star Peter, who wed Abbey in June 2011.
"Peter would love to do strictly," she says. "He loves dancing and loves a challenge so I think maybe when he has finished football he'd like to give it a go."
This year Fashion for the Brave, an annual fundraising event, was sponsored Household Cavalry Foundation and Soldiering On and attended by Princess Beatrice.
