Tracey Eddie screamed with joy from the side of the stage when host Emma Willis confirmed the New Carron singer had received the most votes from members of the public.
The 23-year-old stole Saturday night’s show with a rendition of his own song, Come Waste My Time, which reached the top of the UK iTunes chart.
Now back at work at Callendar Pharmacy in Falkirk, Tracey’s scarcely able to comprehend the weekend’s events.
She said: “It hasn’t sunk in. I’m still floating away on cloud nine. I don’t know where I am!
“Thinking back to the blind audition, I never in my wildest dreams thought we would be standing in a final, let alone could he win it. It’s totally incredible.
“When they said his name, I screamed and my knees buckled.
“What an achievement. It was the most nervous I had ever been because it’s live and there wasn’t any time delay.
“Every step of the way, I feared the worst case scenario happening: I thought he was going to fall down the steps and, ‘What if he forgets the lyrics?’
“I felt I could’ve been sick with nerves.”
Tracey’s fears soon subsided, though, as Craig delivered a stellar performance to claim first place ahead of fellow finalists Grace Holden, Hannah Williams and Okulaja.
Post-final, she spent the evening trying to absorb her boy’s success – and the new environment the pair found themselves in.
She said: “Saturday night was very, very surreal.
“Craig said I was like a schoolkid standing in an after party trying to pretend I wasn’t starstruck by everybody.
“Telling everybody at work, it feels like I’m talking about someone else. When I came home and saw the mess of his bedroom, he’s still just my wee Craig.
“When I catch him on the radio or on the news, he’s absolutely blossoming. His confidence is incredible.”
The backing her boy was given by Scots, particularly in the Falkirk region, has moved his mother.
Tracey continued: “From the bottom of my heart, the support Craig’s been shown is immeasurable.
“You can never thank anybody enough for that. The people who provided posters for free and gave up time to go round the district putting up posters – money can’t buy that kind of support. It’s insane and heartwarming.
“We’re just so appreciative, we can’t express enough how thankful we are.”
Critics often level the accusation at TV talent contests like The Voice that those who win the shows soon fade away due to the weight of expectation on their shoulders.
However, Tracey is positive her son will make any doubters eat their words.
She added: “I feel things are really going to happen for him. He’s broken records set by previous contestants on The Voice.
“He’s gone from the boy who sang in his room, missed the steps in between and jumped up to live television.
“There’s a stigma where you never hear from winners of shows but I think he’s going to go on and break that and prove critics wrong because he has the songwriting, producing and he can play instruments, sing and perform like a star.”
