The prime minister said her husband Philip told her the result of the exit poll and gave her a hug to console her.
British Prime Minister Theresa May admitted Thursday she shed "a little tear" after realising her election gamble last month had backfired spectacularly, but denied she had considered quitting.
According to the head of the British government, she took as much as a few minutes to realize the news.
After calling a general election in April 2017 for June 8th, #Theresa May felt she was going to galvanise the seemingly unassailable lead the Tories had over their Labour opponents.
In the BBC interview released Thursday, May said that although she was aware the campaign was not "going perfectly", she said messages being passed on to her suggested "we were going to get a better result than we did".
Asked if she started to cry on hearing the result, the PM told presenter Emma Barnett, "Yes, a little tear at that moment".
"When it came to the actual result there were a lot of people within the party who had been very close to the campaign who were genuinely shocked by the result as it came through".
A leading commentator called her "Maybot", while her oft-repeated phrases such as "strong and stable, ' "Brexit means Brexit" and 'enough is enough" were lampooned, prompting campaign managers to change course.
May said that she never thought about resigning: "I didn't consider stepping down, there was a responsibility to ensure the country had a government".
She said: "There is a job to be done here, over the next few years".
She said: "Going through that night I was seeing really good colleagues who I'd worked with, who were losing their seats". "I think it was the right thing to do at the time", she said.
Speaking one year after she became the party leader, the prime minister said although she recognised her campaign had not gone well feedback had indicated the party would do better.
"We were the biggest party - we won more votes than the Labour party, more seats than the Labour party - we were the only party able to form a government, and I felt it was our responsibility to do that".
She added: "People can smell blood and that is exactly what is going on in the corridors of power so to speak".
