I’ve lived through the cell phone invention, to flip phones, to smartphones. They were terrible back then and I doubt that’s changed now.

Now, I do understand the reason why you moved back to one. For me, I just got aggressive about notifications and turned off most of them. I stopped social media tied to friends and family and am selective about what I’m on and for how long. Takes more personal willpower (or whatever) but you do get used to it in the long run and feel better.
