Coco Gauff conceded she felt "overwhelmed" in the wake of her French Open triumph, as she licks her wounds after a shock Wimbledon exit.
Just over three weeks on from defeating Aryna Sabalenka at Roland-Garros, Gauff was on the end of a giant-killing at the Championships.
The world number two succumbed to a 7-6 (7-3) 6-1 loss to unseeded Dayana Yastremska on Tuesday.
Yastremska's triumph represented a second straight defeat for Gauff, who went down 6-3 6-3 to Wang Xinyu at the Berlin Open.
And the American expressed some regret at how she has dealt with the aftermath of clinching her second grand slam crown.
She told reporters: "I feel mentally I was a bit overwhelmed with everything that came afterwards. I didn't feel like I had enough time to celebrate and also get back into it.
"It's the first time in this experience. Coming off a win and having to play at Wimbledon. I definitely learned a lot of what I would and would not do again.
"But yeah, also, she played great. I saw the draw and knew it would be a tough match for me. I played her on clay and that surface suits me a bit better and it was still a tough three-setter. I had chances but it is what it is."
Asked what she might have done differently, Gauff replied: "I would say whether I would play Berlin or not again, if that were to happen again after the French Open. Because I only practised two days.
"I just feel like on this surface I could've used more matches maybe. It's like finding the puzzle. I don't usually like to play the week before. It's a quick turnaround. Trying to learn if it's better to train more and then play Bad Homburg or Eastbourne.
"If that time comes around again, I’ll approach it differently. I don’t think it was all that, either. Dayana played great. I felt like I wasn't playing terrible in some points and she was hitting winners. It's a combination of everything.
"This tournament for me is also based off my first round match and my draw. Having someone who can strike the ball as well as she can is definitely difficult coming in."
Across the men's and women's draws, eight top-10 seeded players were eliminated across the opening round, which is the highest tally in a single major in the Open Era.
Gauff's defeat marks only the third time that the reigning women's French Open champion lost in the first round at Wimbledon in the Open Era, after Justine Henin in 2005 and Francesca Schiavone in 2010.
"I'm trying to be positive," added Gauff. "After the match I was struggling in the locker room. I don't like losing. I know my team is going to tell me 'You did well at Roland-Garros. Don't be so upset'. But I really don't like losing.
"I feel a bit disappointed with how I showed up. I could've been a bit better in those tough tiebreaker moments. Especially after Roland-Garros where I feel like I learned a lot in those tiebreakers.
"I'm not going to dwell on this too long, because I wanna do well at the US Open. Maybe losing here first round isn't the worst thing in the world because I have some time to reset. But it definitely sucks."
