The actress, 48, is best known to ITV soap viewers as Ruby Miligan, and regularly shares positive, cheery updates from her private life with partner Ian Kelsey.
Beth has in a relationship with the former Emmerdale star – who rose to fame as Kim Tate’s former flame Dave Glover – for four years.
However, in her latest video, she wanted to reassure her followers that they’re ‘not alone’ after ‘she ‘cried [her] eyes out’ for ‘probably five hours’.
‘I just wanted to say in case this makes anyone feel better, which it might not,’ she began.
‘I’m having a really happy day today but on Saturday I cried my eyes out for probably five hours.’
She went on to list probable causes, from perimenopause, the fact she’d consumed alcohol on the previous evening, and a Generalised Anxiety Disorder diagnosis two decades ago.
‘It might be that I haven’t got that and I’ve got undiagnosed ADHD,’ she continued.
‘It might just be that I hadn’t had enough sleep. I’m not sure. It could be all of those things.
‘We’re all mad here aren’t we. It’s all good now, I just wanted to… you know… in case anyone’s having a bad day, you’re not alone.’
In the caption, she said: ‘I’m not sharing this for any other reason than to say: you’re not alone, this too shall pass, I feel completely mental a LOT of the time and hang in there.’
‘You’re normal. It’s normal,’ she reassured fans.
‘This is me: I’m often thrilled with happiness and other times completely disabled by panic or crying for no apparent reason. I basically think I’m a little bit insane…and that’s ok.
‘It could just be a bad day. If that’s your today then my hope for you is that tomorrow will be kinder. It was for me. Today I’m smiling. Sending y’all a big hug.’
