This doesn't sound superficially like addiction. It sounds more like a mild anxiety disorder, something in the family of OCD. You have to start to feel comfortable with the idea that you will miss out on 99.999999% of all the interesting things to know about in this life, much of it useful. You will be wrong and ignorant about some important things, and it will hurt. All of that is OK, normal, and unavoidable. You just have to get there emotionally. Cutting yourself off of the information hose shouldn't feel scary or inefficient, it should feel good or at least neutral. Your brain needs time to rest, absorb, and find satisfaction in things outside of learning.
