Things that I’ve found help, are less screen time and light exercise. But I find motivating myself to do so difficult. It always seems to help when I do so.
Alice is very intelligent, she's a bit old but not too much. She spends a lot of time on the Internet, and follows pretty much every nut novaxxer you can find. She believes crazy things like "vaccines are made with fetuses from forced abortions", or "Covid is just a common cold", or other conspiracies.
I'm not asking for solutions here. Just sharing this. When I did recently, a friend was almost relieved to know that he wasn't the only one suffering from something like this.
Thankfully, most of the rest of my life is going quite ok. Hope it lasts.
