Strong case, dope flunk

Dope-tainted Pakistan fast bowler Mohammad Asif has vowed to lay bare his "drug dramas" after he tested positive for a banned steroid during the inaugural Indian Premier League in 2008.
Asif felt he was unfairly treated despite having a strong case in the IPL doping episode and said he would one day "tell everything" about what happened during that period.
"I had a very strong case, but they didn't actually listen. Nobody was with me, the PCB (Pakistan Cricket Board) were on the back foot. I was just alone and had to handle the whole thing," said Asif who has just returned to Test cricket against Australia after being banned for a year for testing positive to nandrolone in the IPL last year.
"I will tell everything when the time will come. It's not the right time to tell that," he was quoted as saying by 'Herald Sun'.

He said he thought his career was over after the dope flunk in the IPL.

"It was a very difficult time for me. There were lots of things in my mind in that time. Sometimes I thought I would not be back. That was a tough period, but I continued my training and practicing. Now I am very happy and I am playing good cricket."

Could you please explain to me the emboldened parts?

I know, though, dope means "taking an illegal drug".
