I don't want to turn this into a competitive misery thing because by now everyone is struggling in different ways, but I think anyone who doesn't live alone can't understand what the first few months of lockdown were like for people who did. In the space of a few weeks we went from living normal lives to it being illegal to see
anyone we knew - partners, family, friends, colleagues etc - under any circumstances. Support bubbles and meeting outside weren't introduced until June, so this went on for two and a half months, and at the time there was no set end date.
There was very little contact with any other people except over social media (obviously you could phone people, but even people's best friends usually don't want to talk to them every single day), so staying off it wasn't a great option. But at the same time, it was full of people going on about what a wonderful time they were having with their families, yelling about how selfish and pathetic we were for struggling when we were 'being asked to sit on the sofa and watch Netflix', and making apocalyptic predictions about how lockdown would last for years - laughable now, but at the time it was all completely unprecedented and we had no idea.
And then of course we had the same anxiety as everyone else about the people we loved most getting sick and maybe dying, not knowing when we'd next be able to see them - but with no-one around to share our worries with or to reassure us. Even now I haven't touched another person in several months, and it was breaking the rules when I did.
Again, I don't want to say lone adults have had it harder than anyone else overall - right now I'd much rather live on my own than be shielding or responsible for young children, and there are people living with worse problems than not being able to see anyone for a while. I'm just saying I get why the OP feels the way she does, and I don't understand why people come onto threads like this purely to roll their eyes or otherwise be a dick to someone who's clearly finding things tough right now. But if that's the most fulfilling way you can think of to spend your time then you do you, I guess.
