I think 2020/2021 emotionally exhausted too many people at once. In my case restrictions controlled most of my external social contact flipping my life on and off overnight. By January 2021 I was in a depression and existing my days away. By the spring as life slowly crept open again, the expanse of flat emotion continued. There were several big threads filled with people feeling the same, where the joy of life just hadn't pinged back. I spent 2020 fighting, made the most of what I could in the summer and that 12 hours notice that schools were closing again cracked something inside me.
It's not the only factor, but 2022 was not a year for healing with a flurry of funerals then children having health issues. Life was still erratic and unpredictable.
Many of my friends are in public services so they had the opposite time of being overworked and burned out and really it was 2023 before any of us had the social energy to emerge from the fug of survival mode. They've had their own issues too. At one point due to a friend's life-shit it took 3 weeks to be able to tell them about my family member's death because they weren't in a position to hear about my life-crap and their situation needed more action at that moment. Previously there seemed to be enough ups that someone could give more to someone else's down, whereas we all ended up down together.
Then there's the economy which has been various grades of shit for 15 years which is unusually long. Optomism was growing by 2019 but 2020 kicked that back for years.
Politics is depressing. I can't see any clear, realistic visions of life improving under any political direction at present. Politics and the economy isn't a uniquely British issue and many countries are having similar phases.
I shut the wars out. I hear news headlines, and read the odd thing of interest, but can't be doing with perma-crisis mode and 24hr reporting. The news is pretty monotonous, and I've been around long enough to see various cycles of war. News reporting used to be more factual.
My hormones are probably involved. I notice monthly patterns in my emotional state in recent years. I'm also prone to SAD and have had too few sunny bursts of energy in the past year.
Objectively my life is decent, I know and appreciate what I have, but somehow I lost a glow in recent years and am struggling to find that again and it's not for the want of trying. I miss it.
