What it reminds me of honestly is going through a very very horrible HG pregnancy. I knew it would end, I knew other women had suffered much worse in the past, I knew it was for a good cause, but it was still very miserable to slog through.
There were friends who tried to cheer me up and encourage me to look on the bright side and so on through that and honestly, it did not help. It felt more like they were uncomfortable with hearing ANY negative expression of feelings at all. What helped much more were the people who let me grumble and cry about it without trying to jolly me out of my feelings and said “yes it really IS rubbish, we are going to have a great party once this is over.” That helped me get through it much more than plastering on a bright sunny smile would have done (and probably did make me feel genuinely happier as well).
I agree with this, although in my case it was SPD pregnancies. (Although in the first semester of the first pregnancy it was constant nausea where I longed for the relief of vomit, then the second semester my pelvis gave up. I can well believe the consuming misery of HG)
Both times I knew that it wasn't going to last longer than EDD +14. And there was the "reward" of a baby. An end date does a lot to keep you going.
I went into this knowing that I get cabin fever easily. The dread of the unknown with lockdown looming was awful.
My friends were lovely when I was pregnant. On one occasion a friend came round with her baby already napping and I asked if she wanted to nap and we went up to bed together. 
That kind of social comfort is hard to find at present.
It was a good job that I could't move easily because it saved me from slapping the "pregnancy isn't an illness" smunts. Even when they could see the pain and physical difficulty.
And of course I was in a better position than many people. Despite the obvious pain and limitations, I was ultimately healthy and so was my baby. But that doesn't negate my experience and curiously the more understanding people are those that have had other difficult experiences, and the most dismissive, those that had a pretty textbook time.
As a society we will get back to "normal"
For some people, the details will be little changed. Others will come through with grief, redundancy, relationship breakdown, educational gaps,aggravation of health conditions, abuse etc.
Lockdown increases the risks of these the longer it limps on.
Ultimately we're a social species (and have a contrary climate) so the main structure of society, mass events, culture, big celebrations will always have the demand to return.
And if I wanted a solitary existance homeschooling the DCs with a hermity DH permanantly lurking upstairs WFH, that was viable all along and will continue to be so. I wouldn't be preparing a good foundation for the DC's life though.
