At the PDC Women's Series in October, Sherrock missed out by just two legs on a return to Alexandra Palace where she so famously defeated Ted Evetts and Mensur Suljovic in the 2019/20 event.
The 26-year-old will be among the hundreds of hopefuls at the Marshall Arena in Milton Keynes, starting next Monday, with Sherrock focussed on becoming one of the Tour Card winners.
"It was upsetting at the time but I could either keep getting upset about it or move on from it and that's the way I'm looking at it," Sherrock told The Darts Show Podcast
"I'm using it to make myself more determined. I'm not going to lose by two legs in the future, I don't want to be in that scenario again.
"Lisa winning a Tour Card last year was a great achievement. We all want to get on the ProTour, I want to join Lisa and I know I've got the game.
"I wouldn't be going to Q School if I didn't think I was capable of doing it. I feel like I'm ready for it, I'm ready to be pushed by top quality players.
"I've been practicing a lot. I'm looking forward to Q School so much, I'm looking forward to getting out of the house and playing some proper darts.
"I'm very excited. It will be a very different environment to last year, I don't know what to expect from the whole experience."
Having become a global sensation with her Ally Pally exploits, Sherrock was set for a global tour in 2020 following her inclusion in all the World Series events.
However, the 'Queen of the Palace' remains upbeat, adding: "Instead of dwelling on everything that could've been, I've got to look to the future and see what I can achieve going forward.
"I'm feeling very confident in the way I'm playing. At the Women's Series I really did play some quality darts but missed out by two legs. I think I'll always remember that.
"I know that if I keep performing when I'm in the spotlight then more opportunities will come in the future."
Both the UK and European Qualifying Schools will see Stage One held across two blocks of three days, from February 8-10 and 11-13, before the Final Stage is held from February 14-17.
