Millie Mackintosh's anxiety "spiralled" after she became a mother

She wrote: "Like most new mum’s when I first arrived home with Sienna, I was totally overwhelmed by the love I felt for her, but I also felt very confused by the conflict in my emotions. I’d go from being euphorically happy, to being deeply sad and tearful in the same moment. Hugo would ask what was wrong and I was unable to give him an answer which only made me feel worse as I couldn’t explain these all-consuming emotions.

"There was the irony of feeling so incredible lucky and happy, surrounded by cake, flowers, cards celebrating our adorable new arrival, yet feeling so stormy inside, which spiralled into anxiety as I feared developing post-natal depression (which did not happen), it almost started to take over the most precious time in my life."

And the 31-year-old star knows how scary it can be sharing these negative feelings but urged others to speak out and allow others to rally around them - just like she had her husband Hugo Taylor and their daughter Sienna do.

In the lengthy post on Instagram, she added: "I found that being around nature really helped to boost my mood, so long walks in the park became a daily ritual. I was also very open with my midwife, friends and family about how I was feeling. I know for a lot of people sharing your doubts and worries can feel taboo as you fear that people will think the worst and that you’re not a good mum. For me sharing those worries was a positive experience and I immediately felt those closest to me rally around to support me, Hugo and Sienna. They all checked in daily and reminded me it would pass and in my case they were right."
