Diakite left the UK nearly two weeks ago and according to reports this morning is being treated for depression by the club's medical team.
However, a source has revealed that the 23-year-old Malian international, who is in regular contact with QPR, is dealing with a delicate personal matter and is not battling depression.
Diakite played in the opening two matches of the season, but missed Saturday's 3-1 defeat by Manchester City.
QPR manager Mark Hughes announced in a statement released last Thursday that Diakite had been granted compassionate leave.
"We hope he can overcome this very quickly and get back to being the outstanding player that he undoubtedly is," Hughes said.
"In the meantime, we are giving him the time and help that he needs."
Diakite arrived at Loftus Road on loan from Nancy in January and helped QPR avoid relegation by scoring the winning goal in their 2-1 victory over Arsenal in March.
The transfer was made permanent in June with the defensive midfielder, who was born in France but has won five caps for Mali, costing in the region of £3.5million.
Diakite returned home to France nearly two weeks ago and today [Friday] it was suggested that his absence was due to his battle with depression.
However, the 23-year-old Mali international had been granted compassionate leave to deal with a delicate personal matter and has already resumed training with QPR.
"Frankly, I do not understand why some people start rumours like that," Diakite told RMC Sport.
"I was a bit tired in the last few days and my club allowed me to spend three days in Paris. But I am not depressed.
"My club are my employers and I was in contact with them every day.
"All of a sudden I wake up this morning, open the newspapers and learn that someone has said that I am depressed. This is ridiculous and disappointing.
"I am currently in London and I have been to training, so this is amazing.
"It saddens me because I received calls from concerned members of my family.
"Fortunately I am a strong character as this could have had serious consequences for someone who is weak.
"I want to assure my friends and fans of QPR that I will be at training on Monday with the rest of the group and all is well."
