Conor Benn revealed he was left feeling suicidal after a failed drugs test prior to his planned bout against Chris Eubank Jr. in October.
The 26-year-old saw his fiercely-anticipated fight cancelled following the test results but has since been cleared of any guilt.
Benn was reinstated to the WBC rankings after they concluded his failed test was unintentional and added the positive result could have been due to "highly-elevated consumption of eggs".
The welterweight has maintained his innocence throughout and has now shared that he did not think he would "see another day" after experiencing suicidal thoughts.
"I didn't think I was going to make it through this period, I didn't think I was going to make it through," he told Piers Morgan Uncensored.
"I was shamed for something I hadn't even done, it's hard because I felt like I was on death row for something I haven't even done.
"If I had done something wrong I'm human, I'd raise my hands to it 'I made a mistake', whatever it is, my personal life, I raise my hands.
"Never this, and I felt seven years of hard work and sacrifice and leaving my family and the image I maintain was just ruined at somebody else's incompetence. It's been hard for the family. I didn't think I'd see another day."
Asked if he felt suicidal, he replied: "Yeah, yeah I'd say so, and it upsets me now because I don't know how I got so bad.
"I got in a really bad way about it. You've got to remember, if you think I'm innocent or if you don't think I'm innocent, I am innocent."
