Despite the millions ploughed in to the club by the Malaysian businessman, Rangers' relegation to the Championship was confirmed last weekend with three games of the season still to go.
Fernandes has already confirmed Harry Redknapp will remain as manager as the Rs attempt to bounce back at the first attempt and the chairman insists he is more committed than ever.
Fernandes is also confident business partners Kamarudin Bin Meranun and Ruben Emir Gnanalingam share his passion.
Fernandes told QPR Player: "To all of us, not just me, it's got in our blood. It's the worst feeling in the world when you lose.
"I've been in big businesses and small businesses and experienced many disappointments in life, but there's nothing like when you lose, and nothing like when you win. You're committed in the same way you might be committed to a marriage.
"You have a lifelong commitment in your marriage and we kind of feel that way with QPR that we've got to carry on and realise this dream.
"It's not easy. Many people said to me 'why did you buy QPR and not a bigger club?' And I said 'it isn't really us. We like to build things'.
"It's much harder and I said two years ago there's every chance we could get relegated. But at least we're building something where we can say we did this. You buy Liverpool, you buy a club that's had lots of success, you're buying someone else's success.
"We never expected to be relegated this season but you learn and you become stronger and nothing we've experienced has killed us.
"It's going to be bloody hard in the Championship but we've got to all stick together and go out there and get ourselves out of this mess.
"It's an amazing thing when you see the kind of passion that's in there and it would be fantastic if we can deliver some success to the club for the fans, who have been long suffering.
"It's a job that's not done and so you carry on doing it until you get it done. I see the same passion with Kamarudin and Ruben that I have so we'll continue doing it as long as we can."
