Petra Kvitova has described 2017 as a "rollercoaster" year but the two-time Wimbledon champion is optimistic that she can rediscover full fitness and her best form.
The Czech player suffered a knife attack in her apartment last Decemberand needed surgery on the potentially career-threatening injuries but has since made a return to competitive tennis.
Kvitova, who reached the second round at the French Open on her comeback appearance in May, has admitted she has still not fully recovered but is looking forward to a strong campaign in 2018.
"It will probably take more than a year to get full movement back, I'm not sure," Kvitova told The Guardian.
"For tennis and for life, it's good. I've done everything that I could but there is still some space to improve it. I hope that with more time I will be even stronger. I am happy that [throughout the recovery] I was always looking forward to the better tomorrows.
"This year has been a rollercoaster. The beginning wasn't very nice, so I'm really glad that it's over. Now I can look at everything positively again."
The 27-year-old, who is set to begin the new season at the Brisbane International, has also revealed that she was motivated to prove doubters wrong after some questioned whether she would make a successful recovery to the tour.
"I did hear the rumours that I would never ever play again but I thought: 'I will show them.'
"I was like: 'Why are they saying this?' It was very painful for me, it felt like they didn't believe me. Of course, at that time, I probably didn't know how bad it was because nobody told me - and I am happy for that now.
"My doctor [Radek Kebrle] told me that many other experts thought that I would never ever play. He didn't want to tell me - and that was a good decision for my mental state of mind."
The former world No 2 also revealed that her performances during the grass court season, where she won the Aegon Classic in Birmingham before falling in the second round at Wimbledon, mixed with her impressive run to the US Open quarter-final has acted as a source of reassurance.
"Playing on the grass at Wimbledon and getting a good result in the US Open was very important for me mentally, and for my confidence," Kvitova added.
"It was a pretty tough year and I had a lot of emotions during my comeback. But it has been a year [since the attack] already and I can see that I can play tennis - and I can play it well, and for me this is the best outcome I could have hoped for.
