Joe Wicks has admitted to struggling with his mental health as the UK braces itself for a second wave of coronavirus.
The 34-year-old fitness expert became the nation's PE teacher during lockdown earlier this year, streaming free daily exercise classes on YouTube to an audience of millions.
The UK government has eased restrictions on social activity in recent months as the threat of the virus subsided but is now being forced to tighten measures again as the number of positive cases of COVID-19 rises.
"I'm hoping that by sharing how I'm feeling and struggling, really struggling, there could be someone out there right now who is feeling the same and I want you to know that's OK," Wicks told his followers in a video message.
"I've just finished watching the press conference with Boris Johnson around the new covid restrictions. Now this is really starting to take effect on my mental health, it's bringing me down. I'm finding it confusing I can't comprehend where the end is.
"I'm finding it hard to be optimistic. That feeling of powerlessness, confusion, it's a hard feeling to deal with. With the realisation that this isn't just going to go away tomorrow, it's really getting me down.
"The one thing I love more than anything is being connected with community. My mum, my dad, my grandparents, my family and friends, I love being around people. This is disconnecting me from my work colleagues. I understand why but it doesn't make it any easier.
"I'm personally getting sensitive about other people. When I start thinking about all the people that are going to be affected. Knowing that small businesses are going to go under, I'm finding it very hard to be motivated to film workouts and do anything."
In addition to his YouTube workouts, which are now done on an occasional basis, Wicks is also hosting his own podcast series for BBC Sounds.
