I do find myself aimlessly scrolling sometimes and feel like some sites are damaging for my mental health. I find Instagram ok because I only follow accounts that make me happy, have great content or motivate me. I had to come off Facebook a few months ago because I find that when I see a sad story, involving murder/children etc, my brain will think about it for days/weeks on end and just won't shut off. I find Facebook really negative in general, lots of ads, posts I don't want to see, arguments or negative upsetting posts.
