Jesy Nelson battled with secret jealousy before she attempted to take her life.
During her Capital FM interview on Thursday, the No More Sad Songs hitmaker admitted she become consumed by envy shortly before her secret suicide attempt.
At the time, the Little Mix star, 28, was comforted by her bandmates Jade Thirlwall, Perrie Edwards and Leigh-Anne Pinnock.
But the songstress also watched her friends live their best lives and be happy while she sunk into the depths of depression.
Jesy told how it ignited the green-eyed monster inside her because she wanted to know what it felt like to feel happy.
She said: "I was so jealous and envious of how happy they were. I just wanted to know how it felt to feel happy."
The redhead expressed she felt like a burden on her bandmates while Little Mix were soaring to the heights of fame.
Jesy confessed she nearly walked away from the four-piece band and gave up her dreams after the cruel taunts took their toll.
She elaborated: "Yeah [I nearly left the band]. For them [Perrie, Leigh-Anne and Jade], it was hard as well. They're living their dream.
"To have someone constantly down and depressed all the time, you don't want that when you're living your best life. It was hard to be happy and console me at times."
Jesy found it hard to keep to her jam-packed schedule as she missed work and shows.
The Power hitmaker documented her panic attacks and how she believed people in the crowds were talking about her.
Jesy recalled how she felt when she didn't want to see her friends or go to work anymore.
"I didn't want to go out with my friends or go out to work, I didn't want to perform, if I'd see people in the crowds pointing and whispering. I'd have panic attacks." She said.
"I've just felt very isolated, very vulnerable. Obviously, don't get me wrong, we've all dealt with online trolls."

She said: "She saw how happy I was to see this confident bubbly girl to go to someone she didn't recognise. It was really hard as she wanted to take me out of it.
"I thought I'd only make it worse for myself. I didn't know what to expect. It was a never-ending spiral."
