Robin Soderling has revealed his determination to return to the ATP Tour despite his long-running battle with a viral infection.
The former world No 4 has not played a competitive match for 18 months after being diagnosed with mononucleosis.
The two-time French Open finalist admits he may never win his fight against the fatigue virus, and that he has suffered a number of setbacks in his bid to resume his tennis career.
“The hope, the hopelessness, then the hope again, then the hopelessness – that really kills me,” said the 28-year-old Swede.
“I feel really good, then I start to practice, and then I think maybe in a couple of months I can come back and I really believe it. Then I do a bit too much and wake up one morning not feeling well again.
