So with our 'old lives' dangling frighteningly out of reach for an unimaginable timeframe, how can we navigate the blurred line between loneliness and solitude?
Follow a daily routine
It's all too tempting to bury our head beneath the covers after a quick scroll of the morning headlines but creating a daily routine (and getting dressed) will trick your brain into thinking it's just another day.
"We might not be able to control what's happening outside but we can control what's happening in our house," Tebbey stresses.
"Plan to get up at a certain time and maybe incorporate some exercise into your schedule before work. A daily routine makes it easier to cope with all of the uncertainty that's surrounding us."
Make solo plans
We're all craving the simple pleasures we once took for granted from shovelling popcorn at the local cinema to signing up to a packed pilates class filled with sweaty, happy strangers.
But solitude doesn't have to equal loneliness - something London-based journalist, Francesca Specter, knows all about.
After discovering there wasn't a word to describe "celebrating and valuing the time you spend alone", she came up with one: alonement.
"Plans don't have to involve other people," Specter, who founded the Alonement podcast, told marie claire. "Calendarise solo time - even if it's just a movie night in or doing a yoga video - so you have something to look forward to."
Look after yourself
Even if you're confined to your house and are heavily relying on the goodwill of neighbours, you don't need much to feel a whole lot better - whether that means reading book-after-book in a bubble bath, taking a breather from the news or buying yourself some flowers.
"Practice simple self care - a cleaning regime, washing your hair regularly or making sure you go to bed at a reasonable time," Specter advises.
"Little things go a long way at keeping your attitude positive and staying mentally resilient."
Connect on a digital level
In recent weeks, we've seen the true power of social media play out with friends and families staying connected more than ever before all thanks to apps including Houseparty and Zoom.
Whether it's a dinner date over FaceTime or a wine-fuelled quiz night on Facebook, seeing friends' pixelated faces is sure to help you distinguish the difference between Monday and Friday.
"We have amazing technology at our fingertips now and we're starting to see this incredible trend of people talking with friends more than they ever used to," says Tebbey.
"We have people hosting dinners over Skype, tagging along to trivia events being run on Instagram Live... it's amazing what social media has to offer in times like this. Everybody needs to make their own judgement on what they want and need during quarantine - it's ok to ask for help."

Keep a quarantine diary
One of the simplest but most effective ways to boost your mood is to practice gratitude every morning whether it's giving thanks for the care package a friend left on your doorstep or taking a moment to appreciate the fact the sun is shining.
"Use this time to get more in tune with your emotions," says Specter. "Writing a diary every day helps you to connect with your inner voice and can tackle any negative thought patterns."
Give your loved ones a call
Sometimes reaching out to others is one of the easiest ways to feel good and serves as a reminder that the coronavirus pandemic bears no boundaries and has impacted us all, no matter who we are or where we come from.
"There's a real vulnerability out there that we need to be aware of and it's really beholden of us all to be aware that not everyone is as tech-savvy as us whether it's elderly neighbours or grandparents," Tebby adds.
"It's not difficult to pick up some groceries for someone who can't get out for themselves," he continues. "Reaching out, connecting and looking out for those around us is what we need to be doing at the moment because we're all in this together."
