I really truly suggest diversifying to newsfeeds without comment sections like techmeme for a bit.
Increasing complexity is overwhelming and theres plenty of bad shit going on but theres a lot overblown in your post.
Sorry for the long edit: i personally felt improvement for my mental health when i did this for 6 months or so. Because seriously, whatever disinformation is happening in american news is so exhausting. We need to think whatever we want and then engage with each other when our thoughts are more individualized. Dont be afraid to ask questions that might seem like you are questioning some holy established lemmy/reddit consensus. If you are being honest about your opinions and arent afraid to look dumb then you are doing the internet a HUGE service. We need more dumb questions and vulnerability to combat the obsession of appearing as an expert. So thank you for making a genuine post of concern.
