Please tell me to go study if you see me fooling around in different threads.

I relate to your struggle with distractions while studying. It's frustrating when interruptions derail your focus. Isolating yourself in a room for clarity resonates with me. A structured environment to tackle brain noise would be beneficial. Living with parents presents challenges to create a focused space. Your experience inspires me to consider a similar method when I live alone. Thanks for sharing insights and validating those grappling with similar issues.
