I'd sort of compare this to the stages of grief.
I have been through denial (just trying to pretend life is normal, even though I'm stuck at home and have no job), bargaining (well if everyone sticks with the restrictions, then of course we can all go back to normal, I'll do my part etc), depression (how I feel now, probably not entirely to do with Covid-19, but I guess it reinforces it). Anger not so much, since it's not an emotion I feel so much (apart from at myself, occasionally).
I don't live in the UK and am living under much stricter conditions, but I don't see what being angry would achieve. During the last month I've lost one family member very close to me, as well as another one. Lockdown or no lockdown, that would have happened. I am sad I can't go out, and don't have the ability to just book a flight somewhere and try and escape from everything.
But Covid-19 is not really about the individual, it's about something that can destroy families, cause premature death, and disrupt our way of life.
I'm not angry, but I am sad. But this is a global pandemic, and the world is much bigger than just me.
