I have some pretty bad internet addiction too. It was so bad I basically stopped playing guitar in my teen years. I restarted last year and had to basically start from scratch, it was so depressing. I used to be able to sight read sheet music, then I threw a budding life skill all away to look at memes I will never remember or play some dumb quest in a game.
I was addicted really to consumption. I stopped creating. Now I'm trying to make more time for it. The other night I fell asleep on the couch before midnight with my guitar in my hand and my fingers forming a chord, rather than being wired and awake on reddit until I look and notice it's 2am again. Still, the sting of knowing I squandered probably 10 years of youth just consuming junk is a lot to bear.
It's depressing knowing some very smart people are out there striving as hard as they can to get me and others away from looking inwardly and creating, or at least investing focus in one's own life and building yourself up, and instead hooked on the teet of endless content. It's like the end game with this endless consumption is The Matrix, where most of humanity is just plugged into the machine sitting there, thoughtless, sucking on the feeding tube and fueling the robots until they eventually die and are replaced by another warm body.
