Speaking via video link on Friday’s Loose Women, John said that things got so bad at one point that he would ‘sit in a room and sob’.
The former Doctor Who star didn’t even tell his family about it over fears they would worry about him.
‘I wanted to go to someone who didn’t know me and didn’t have a preconceived image of me,’ he began.
‘I was doing that until I came back over (to the UK) every week for about the last four to five months.

‘Saying this on here, my parents and family didn’t even know was going.
‘You’re the first ones to know about it, Scott knew but it was really nice to be able to talk to somebody who I can just say vomit everything out to them ant not worry about them judging.’
‘It helped me to sort it out and figure it out because I was becoming cranky, crabby, it was hard,’ he added.
‘I was going into a room and just sitting and sobbing because I’d been so used to working all my life and all of a sudden, one day it just stopped.
‘There was nothing to do. I didn’t know what to do with myself.’

Another praised: ‘Keep talking John. Thank you for being so open.’
While one added: ‘I really didn’t think I could love and admire @JohnBarrowman more but I do…’
