Why is it impossible to quit social media ?

I guess it's harder for old people to understand but as many may know, social media can be pretty addictive.

At first it wasn't entirely addicting but it's gotten that way over the years. I have soo many instagram accounts... And I have Facebook of course.
I have 1 "personal" instagram where I upload random photos on things I do and the occasional selfie. I have one for poetry, one for photography and two each for my pets.... The ones for my pets weren't my idea, my mom basically made me make them.. My two "art" accounts or whatever serves a purpose yet those are the ones i'm least active on. I'm just on my main all the time, scrolling worthless shit and being braindead, sometimes uploading a random photo... And why do I use Facebook ?!I literally never make a single post aside from sharing my favorite songs, links probably no one clicks on. I update my profile pic sometimes, then feel upset when no one likes it or too few people do as if it matters. Now I genuienly need Facebook for some of the groups i'm in and Marketplace is pretty useful but there's no logical need for scrolling everyday for no reason.

I've considered not logging in to my main instagram account where I don't do anything useful, and to never go on Facebook unless I really need to but I wonder if people would wonder why. I guess on my main I can post photos of doing something fun or looking extra nice sometimes because otherwise, no one would see it... I am lonely. I don't know why the instinct to scroll worthless crap is so intense though, rather than doing something useful on the internet at least. It has a very negative effect. I've started envying my friends who post photos of having fun times even though it's my choice to not do anything myself. Stuff like that.

Did anyone here quit social media addiction ?
