Viewers who tuned into Kelsey Parker: Life After Tom were left in tears after watching Kelsey's journey through frief.
Her husband Tom Parker died at the age of 33 in March after battling a brain tumour.
The singer left behind Kelsey and their young children Bodhi, two, and three-year-old Aurelia.
During the ITVBe programme, Kelsey opened up about the struggles of living life without him and hearing The Wanted's songs.
At one point, she admitted she is no longer able to listen to his band's songs even though her children ask for them.
She also said she never knows how to respond to the 'how are you' questions when people approach her.
Kelsey also had to prepare for what would have been his 34th birthday and planned a charity run to raise money for brain cancer research.
Viewers of the programme were emotional watching Kelsey and took to Twitter to share their thoughts.
" #lifeaftertom had me really emotional and my heart really does go out to anyone who loses a loved one especially by cancer," one user said. "I know Kelsey hates people saying this but she really is so strong."
Another added: "Heart breaking and emotional watching #LifeAfterTom so proud of @Being_Kelsey opening up and talking about it. Helping so many other people who are grieving losing friends & loved ones. Dealing & process with it."
"What a difficult watch!! Some happy moments of laughter and some moments of me busting into tears!" one viewer commented.

"Absolutely broke my heart all over again watching that," a fan posted.
Kelsey admitted she no longer listens to The Wanted while listening to a recording Tom made before he died.
While sitting on the floor in her bedroom, she said: "I can't listen to The Wanted songs, I can't do it. The kids want to play Glad You Came.
"And I'm like, 'No, Glad You Came is banned'. Tom was the most amazing singer and I just loved listening to him."
"I find it so hard now when I find his music. He was just such a talented, talented man. He would just sit in his studio for hours on end just playing the same bit of music, like the same eight bars on repeat and it used to drive me absolutely crazy."
