I would have to agree, I also gave up Instagram/Facebook because I noticed it impacting my mental health.
The only thing I miss is the early days of Facebook when it was just humans being human, and posting pictures of them being silly or with their family instead of flexing about newly acquired money/status, etc. But maybe that's just me remembering with rose tinted glasses.
Personally it's hard to understand if quitting SM changed my emotional response to a lot of things or if it is me who changed in time. It doesn't help that the agenda and techniques used by these platforms evolve all the time to find new ways to hook you in
