Ben Woollaston admitted his confidence deserted him during his 10-4 defeat by Ali Carter in the first round of the World Championship.
The 25-year-old from Leicester impressed in the first session and could easily have been ahead.
But he trailed 5-4 and the ruthless Carter did not drop another frame.
"I enjoyed the first session because I played reasonably well but after that I just couldn't do anything right at all," the Crucible debutant said.
"There wasn't that many nerves. I was most nervous when I played well to go 3-1 up. I just lost my confidence."
Woollaston got himself in frame-winning positions on several occasions, but missed a couple of relatively simple colours and two-time World finalist Carter took full advantage.
"It was a bit embarrassing really," he said.
"I didn't play well at all. If I had played like I did in qualifying I would have probably come close to winning or won."
The Crucible qualifier, who often practises with Mark Selby, hopes his first World Championship venture will help his development and is already plotting a return to the home of snooker
"It's great out there but difficult to keep your concentration," he added.
"Hopefully I will learn and do a better job next time. I can compete with anyone if I play to my potential but it's just doing that often enough."
