For me lockdowns were a period of our history, not our present.
I worked 80hr weeks for the first 5 weeks of lockdown, not knowing if the business I worked with would survive and the following 4 weeks I works 65 to 70 hrs per week. I look back and wonder where I found the energy but with a sense of pride that I cared so much. And no, I’m not looking for a medal - I am simply describing that it was physically hard going.
My DH faced similar uncertainty with his business, but used that certainty to question and probe what could be different and better if it survived.
Our kids (a teen and pre-teen at the time) were feral in those 9 weeks. They home schooled themselves or didn’t some days during those 9 weeks. My oldest was diagnosed with a living changing, chronic health condition during this period, his life is forever different as a result and that is bloody tough.
My memory of sunshine and lovely weather is vivid though I wasn’t out in it but our kids were out in the garden every day loving it.
My Mother is different post lockdown as she because very anxious about contracting COVID but if I am to be completely honest there is evidence of moderate health anxiety being present throughout our childhood. It was COVID that changed her not lockdown though it was hard for her - she adopted her own version of COVID protocols that were very self limiting and nobody could talk her down from them.
While I would not wish to return to a lockdown period in the future I would take 10 lockdowns than live where war atrocities are happening.
Our governments made decisions in the moment, some were positive and worked while others were poor and ill considered - I don’t believe any were made with malicious intent (I am not referring to some individual politicians who behaved atrociously).
OP, like others I think you’re describing something beyond an impact of lockdown be that depression or something else.
Speaking with a professional therapist could be really worthwhile. For my Mother, I wish she had sought counselling with she was younger to address what I believe to have been health anxiety in her case. I really believe it would have helped her resilience for what live brings which just happened to include a pandemic. And selfishly, it would have helped her adult children which as a Mother she would also have wanted.
Look after yourself
