I am sorry to hear about your mental health challenges. I struggle with those things too.
I would say yes, MN is definitely social media, although it differs from other platforms such as Facebook and TikTok as it doesn't seem to have those algorithms which keep pushing content at users that can lead them down unhealthy rabbit holes.
I have noticed that my engagement with MN, on a number of levels, varies depending on how well I am doing at the time.
Once when my anxiety was high, someone on here accused me of being anti-Semitic, based on a post I wrote.
Other people told them they were mistaken as the politician I was being rude about is not actually Jewish. Of course, bigotry hadn't been my intention; I was criticising his policies, but I shrank from the attack and ran away from MN and didn't come back here for ages.
Whereas when my mental health is good and robust, I am much more resilient and can engage with dissenters without taking it to heart and feeling terrible about being disagreed with.
Overall MN has been much more good than bad for my mental health. I can choose which topics and conversations to engage with and there are some really wonderful, kind, wise, intelligent and funny people on here.
Sometimes if I am very anxious and am isolating myself to the point of agoraphobia, posters on here are the only adults I engage with all day. It is reassuring to see the same names popping up with their comments, and I feel you get to know a little bit about the person behind the username.
MN makes me feel part of a community of good women and that is definitely beneficial for me.
