Replying to Has social media made you retarded?

I feel that ever since I got a smart phone my freshman year of high school, about 7 or 8 years ago, i either developed ADD or it really began to show its affects. I find myself not being able to focus on school work, only stuff that i really have an interest in doing. i also think that social media has created an addict in me, and I find myself picking up my phone whenever i don't have any immediate thing to focus on and just swiping, sometimes even opening an app i just closed just to swipe more and realize "wait wtf i was just on here". Like its muscle memory.
My friends pressured me to get snapchat again (haven't used it for like 5 years now) and i used it for 2 months. Never felt more distracted and like a relied on my phone so much. I try to keep the instagram app off my phone and only use it on the browser to check messages, but i have a hard time staying away from it. Deleted twitter a couple of years ago luckily and have no desire to go back to it.
How many of you feel addicted to a social media, and have you been able to quit it? And how? Im trying to get more control of my brain and my life and i tend to fall back into the same routines and find myself slave to old habits
