Iga Swiatek admitted she felt awkward about not being able to be honest regarding her absence from the tour.
The Pole failed a doping test in August and served a one-month ban after it was accepted medication she was taking to combat jet lag was contaminated.
That news was not announced until November, when it emerged she had missed three tournaments in the autumn while serving a provisional ban, which she attributed at the time to personal reasons, fatigue and a change of coach.
Following so soon after the announcement in August that men’s world number one Jannik Sinner had failed two tests in March that were not made public at the time, it was another major blow to the sport’s reputation.
Speaking ahead of the Australian Open, Swiatek said: “The first three weeks, I would say, were pretty chaotic. There was no way to have any answers to the questions. We just focused on finding the source.
“But I’ve got to say, for sure it wasn’t easy. It was probably the worst time in my life. And the fact that I had no control over this whole situation and I had no chance to avoid it, it made it even worse because I’m a control freak a little bit.
“Just having the feeling that everything that I kind of built can be taken away so quickly because of something you have no control over, it was pretty crazy for me and really abstract.
“After, it got pretty awkward. We chose for the first tournament to say personal reasons because we honestly thought the suspension is going to be lifted soon.
“From the beginning it was obvious that something was contaminated because the level of this substance in my urine was so low that it had to be contamination.
“Since we didn’t know what’s going to happen because we had no control over ITIA’s (International Tennis Integrity Agency) decision, we also couldn’t make any logical plan. We started with personal issues because I needed also time to figure everything out.”
She admitted she was fearful of what the reaction would be but thanked rivals for their support.
“Besides the fact I couldn’t play, this was the worst thing for me, like what people would say,” she said. “Because I always worked hard to be a good example, to show my integrity, show good behaviour.
“Again, having no control over this case really freaked me out a bit. But in the locker room, the girls are great. I already saw at this exhibition in Abu Dhabi (in December) that they are really supportive.
“Most of them even approached me. They’re like, ‘Hey, how can we avoid this? Is there any way that we can be more careful?’ They are worried this can happen to them, as well.
“There are many top players – I’m not going to say names – that are really supportive. I really appreciate that, because it made me feel better when I came back and I didn’t know how it was going to be.”
Second seed Swiatek will take on Czech Katerina Siniakova in the opening round in Melbourne.
Emma Raducanu, meanwhile, revealed she refused to use an antiseptic spray after an allergic reaction to being bitten by insects on Thursday because of fears regarding anti-doping.
“I’m allergic, I guess. They flared up and swelled up a lot. Someone was giving me this antiseptic spray, natural, to try to ease the bites. I didn’t want to take it. I didn’t want to spray it.
“I was just left there with my swollen ankle and hand. I was like, ‘I’m just going to tough it out because I don’t want to risk it’.”
