It's very odd, I use to use Instagram and it would make me depressed. IDK how to explain, I don't even have any friends on there I follow. Just something about seeing everyone at their best 100% of the time, doing amazing things 100% of the time, never facing adversity 100% of the time. I know it's not realistic but it still gets to your head. I uninstalled it from my phone I feel better about myself after a few week…
On the other end of the spectrum, Facebook used to be a cesspool for me, since I didn't like the amount of politics and high school classmates I didn't like in high school in my feed. Then, I unfollowed everyone that posted any politics of any kind, unfriended people I intended to never see again, and now my feed is only a handful of groups that are incredibly friendly and helpful communities around overly obsessive coffee culture. Otherwise, I now use Marketplace pretty heavily since it seems to have largely replaced Craigslist in my area with better targeting that actually regularly gets my interests right. Now that I have made the choices to use the tool well, it's really really helpful. You have to take some responsibility for the bad experience you have on these platforms -- they only push you content you engage with, so you can choose to stop seeing that crap if you want to.
