Speaking to The iPaper , Marler said his depression led to struggles getting out of bed each day. “Me constantly crying on the way to work, stuff like that,” he explained.
He admitted he would direct his emotions, which manifested into “rage and anger” out on Daisy, his wife of eight years, with whom he shares four children: Pixie, Maggie, Felix, and Jasper.
After going to therapy and taking antidepressants, Marler is now looking after his mental health and has developed techniques to recognise triggers and control his anger.
