Celeste Barber reveals she's 'spiralling' months after split from husband Api Robin

has given fans a candid glimpse into what she .

The Australian comedian, 43, took to Instagram to share a carousel of seemingly random snapshots from recent weeks, including a striking selfie of herself lying in bed with a white cloth draped over one eye. 

She appeared makeup-free in the close-up image, staring solemnly at the camera.

Alongside the post, the actress shared a tongue-in-cheek caption listing everything she blamed for her latest downward spiral.

'This chapter of my spiral brought to you by,' she wrote, before rattling off a string of humorous entries.

'Stress sty. Wine. Booie. Janet. Tits. Knicks. Art. The King. Anxiety. BOOIE. Inside. Relatable. Company. Birthday Betty. Influencing.'

The post also included a series of photos showing four half-finished glasses of red wine gathered around candles, a close-up selfie of Celeste applying lipstick while wearing oversized clear-framed glasses, and a mirror selfie in an oversized blue New York Knicks T-shirt paired with loose brown trousers and burgundy sneakers.

Despite the cryptic nature of the upload, fans quickly flooded the comments section with messages of support.

Celebrity chef Nigella Lawson wrote: 'Oh darling. Sending all the love'.

Television presenter Lisa Wilkinson added: 'Take it easy you wonderful woman.xx'

Journalist Kathy Lette also chimed in with her trademark humour, joking: 'Yikes! Administer Vegemite on toast immediately! ❤️'

Others praised Celeste's honesty.

'That's a proud Dad,' one follower wrote.

Another added: 'Spiral is my favourite kind of perm. Love you, lady love. Sending enormous cuddles.'

A third commented: 'I know it's painful but know one day you'll breathe easier and understand the reason behind all this chaos. Sending you lots of love. You will be okay just like me and many others.'

The post comes months after Celeste while sharing a video of herself doing a 'five minute Pilates' workout.

In the clip, she lip-synched to Alanis Morissette's 1995 heartbreak anthem You Oughta Know, a song about the emotional fallout of a relationship .

'Feeling pretty f***ing hardcore doing 5 min Pilates and blaring @alanis,' she captioned the video, before joking in a follow-up clip: 'I don't even need the backing track @alanis.'

The upload came shortly after Celeste publicly acknowledged the outpouring of support she received following news of her separation.

While promoting a mascara from her makeup brand BOOIE on Instagram Stories, she paused to quietly thank fans.

'Thank you for all your lovely messages. I really appreciate it. Thank you,' she said.

Api confirmed the couple's separation in February, just one day before Valentine's Day, after 20 years together.

'The past few months have been incredibly challenging and deeply heartbreaking for us both,' he wrote in a joint statement.

'After much reflection, the decision has been made to separate.
