I can relate. I'm trying to use social media in a positive way, although I do often find myself doom scrolling when I want to avoid something. I try hard to use it creatively and not concern myself with how what I make is received. As I practice that philosophy, I pass it on to my son, aged 16 and also autistic, like me. It's really helping to form a tight bond between us.
I've been publishing my writing on my own website rather than on social media. Maybe Hive would be a good place for it too. I'll think on that.
