Miranda Hart has given a rare insight into her three decade mystery health battle and the moment she received her official diagnosis – she has Lyme Disease The comic officially received the diagnosis in lockdown and believes she contracted Lyme Disease when she 14 after battling nasty flu like symptoms in Virginia The comic officially received the diagnosis in lockdown and believes she contracted Lyme Disease when she 14 after battling nasty flu-like symptoms in Virginia. She writes: ‘For me it was the unnerving neurological symptoms that I had got initially, aged fourteen, from Lyme, which I always found particularly hard to deal with. And they got considerably worse as I headed into my forties. As did the fatigue from the cell depletion. Yup, all delightful.’Of the moment she got her diagnosis, she adds: ‘I got off that Zoom call, pulled my laptop shut and sat there, still and aghast. So many emotions, I was shocked, but I also immediately felt a deep well of sadness and disappointment – for over three decades I’d KNOWN there was something wrong. I recalled all the times I’d told different doctors, “I feel toxic and poisoned, or, It’s like I have flu every day but I don’t have a temperature.”‘(It’s amazing how the body can sometimes literally tell us what’s going on.) I felt anger rising at the times l’d been told I must have agoraphobia. ‘I would try and treat it as such, when, as it turned out, it was the lack of energy and the extreme light and sound sensitivity that made my body crash when going out to be in any kind of activity or stimulating environment.’Miranda says she struggled to know how to share the news of her diagnosis with her followers, fearing she would be perceived as ‘complaining’ or ‘just tired all the time’. But Lyme Disease was causing havoc for her body and she ended up with ‘endless diagnoses’. Also, fans soon noticed her absence from TV screens. In 2017 it was revealed Miranda would not be returning to Call The Midwife, citing a busy work schedule as her reason.But she later revealed during an stand-up gig in London that she had been suffering from ‘ill’ health.She said at the time: ‘I don’t feel myself at the moment, because I was ill last year and I wasn’t able to exercise.’  While fans know the comedian, 51, as Chummy in Call The Midwife, Miranda has admitted behind closed doors she was desperately telling doctors: ‘I feel toxic and poisoned’ Excerpt taken from Miranda’s memoir I Haven’t Been Entirely Honest With You – out Thursday October 10 In 2017 it was revealed Miranda would not be returning to Call The Midwife.

That’s why I eventually collapsed.’Reflecting on the life-changing moment, Miranda says if she had learnt to remove stressors from her daily life, ‘my body could get back to some efficient functioning to recover’. The star also suffered the ‘excruciating sadness’ of losing her beloved dog Peggy in 2021.Miranda had had Peggy, a shih tzu-bichon frise cross, since 2007 and credited her with helping her through tough moments in her life, including past heartbreak.She announced the death of her ‘loyal, loving best friend’ on Instagram and said she was taking a break from work and social media.She later went on to get a new dog, a Poochon called Patti, which fans described as her ‘healing dog’.Excerpt taken from Miranda’s memoir I Haven’t Been Entirely Honest With You – out Thursday October 10. WHAT IS LYME DISEASE?
