Gillings, 24, finished eighth in the snowboardcross on her Olympic debut.
Afterwards she revealed that a knee injury hampered her chances of progressing through her semi-final, where she finished third and had to settle for the B final.
It completes a turbulent season for Gillings, whose training was severely restricted due to national governing body SnowsportGB's financial strife which saw them go into administration just a week before the Games.
The British Olympic Association stepped in to ensure the 14 athletes who were SnowsportGB's responsibility could at least compete in Vancouver.
That was just a short-term fix however and Gillings cannot wait to team up British Ski and Snowboard as she bids to top the podium at Sochi 2014.
"I have learnt a great deal from the past 12 months and will not let it happen again, I'm making absolutely no excuses as I did what I could with what I had available and I'm happy with eighth place," said Gillings.
"It will make me stronger and more determined to become the best.
"I'm leaving here now with one goal in mind, to become the best in the World over the next four years with a World Class programme to match.
"The British Olympic Association have been awesome in helping me prepare for these Olympics and I'm really looking forward to working with them towards Sochi.
"It will be a welcome change working with a truly professional body such as British Ski and Snowboard who have now taken over as my new governing body and I have 100 per cent confidence in them. I'm now more determined than ever."
An MRI scan after the competition in Vancouver revealed tendon damage in Gillings's knee whereby she is currently on crutches for the next three weeks but there is not thought to be any long-term damage.
She added: "I want to ensure I fully recover from this injury as I know so many people who have repetitive knee injuries throughout their career, I should be okay in three or four weeks but I'm not taking any chances."
