'We now are in a transforming world. It will take us a while to be able to articulate to ourselves what the result of that has been on us as individuals, and I think it’s really important - I feel it personally - to take the time in solitude, in quiet, to figure out how you have changed and how has it affected how you look out on the world and what your mental health is because I’ve felt it dramatically.'

Last week, the 74-year-old actress spoke candidly about her childhood trauma.

When she was still a child, Glenn's late father, Dr William Taliaferro Close, became enamored with a conservative new religious group Moral Re-Armament.

Eventually he moved the family to the organization's headquarters in Switzerland, effectively cutting Glenn off from the life she once knew.

Speaking about her traumatic experience on the show, Glenn said: 'I was in this group called MRA and it was basically a cult, everyone spouted the same things and there's a lot of rules, a lot of control.

'Because of how we were raised, anything you thought you'd do for yourself was considered selfish. We never went on any vacations or had any collective memories of stuff other than what we went through, which was really awful.'

Detailing the impact this had on her mental health, Glenn explained: 'We were so broken up. It's astounding that something you go through at such a young stage in your life still has such a potential to be destructive.

'I think that's childhood trauma, because of the devastation, emotional and psychological, of the cult.'

Glenn, who has been married three times, added: 'I have not been successful in my relationships and finding a permanent partner and I'm sorry about that.
