Trauma and stress impact memory: short term and long term. The effects might not be permanent, but then we don’t really know what continued trauma can do to parts of the brain, we’re still learning.
Bottom line: if you feel like you have brain fog? – you might have it, I think I have it … I think a lot of people I know have it. If you think I have the magical explanation for this? – I do not. I can only suggest that you unplug a bit. Get a flip phone, take more walks sans technology. If you can afford it, adopt a dog. Maybe a cat. Cooking isn’t just about healthier ingredients, it’s also about switching attention to something that doesn’t involve WW8-death-butt-viruses.
Cut yourself some slack, just not too much.
