They're not remotely comparable imo, OP.
The 2008 crash had a lot to do with greedy bankers in the US lending money to people who would never be able to pay it back, and it all coming in top. The fallout was essentially economic, as were the remedies, although I concede it was a worrying time.But for a lot of people in the UK, life went on as normal, job losses were relatively low (approx 200k, iirc) and the vast majority of those (in the UK, at least) were in the financial sector, so the impact wasn't as great.
It was also a long time coming. There was a lot of talk and (iirc) one or two former building societies collapsed early in the year, then it all kind of quitened down around budget time, and all the talk and anxiety was more about what was happening in the US financial sector. But it wasn't until much later, late summer or early autumn, that things really went tits up. We were also very lucky in having Alistair Darling as chancellor, he turned out to have balls of steel beneath his unassuming demeanour.
This is more akin to a natural disaster, that feels like it may be beyond our control, and that could cause a huge number of deaths. It's unpredictable, it makes us scared in a much more primal way.
We can't carry on and leave it up to others to sort out, we have make decisions that could turn out to be critical, several times a day. Our survival could depend on whether the person who gets in the lift with you has taken their sore throat and temperature seriously, or thinks they're too important to self-isolate.
So much depends on the science, if an effective treatment and/or vaccine can be developed, tested, manufactured and used before the numbers affected overwhelm the health care services across the whole planet.
And it can totally fuck the economy while it's happening, so it's the worst of double whammies.
And the other big difference was that the 2008 crash came at a time when our public services and infrstructure were in relatively good shape and our social welfare provisions were more or less adequate. This is happening after 10 years of cuts in public spending, when the system is groaning under the strain and barely able to meet normal demands, let alone exceptional ones.
In 2008, I felt philosophical, and understood that things would be tough but confident things would be ok in the end. Now, I feel pretty scared, and really anxious for friends, family, colleagues. My DSS could die, ffs, he's type 1 diabetic and is a bit laissez faire about monitoring his levels, and he does a demanding, physical outside job that brings him into contact with a lot of people. He's 29, with a 4 YO daughter - I'm worried for him, and for DP, who would be beyond heartbroken.
This could take people I love. The global crash never made that likely.
Sorry for the essay.
TL:DR: not similar in any way, at least for UK citizens.
