pmo has fried my brain. no mental clarity

Have any of you experienced mental benefits in terms of your academics and doing well in school / mental focus and the ability to think more clearly? I for one feel like pmo is to be blamed for some of my recent shortcomings, as I often can't find the motivation to do well in school and study, its almost as if I just want to sit around and watch anime all day /watch porn and jack off. Even while walking throughout campus, I have fantasies of having sex with virtually every female student on campus. If so is there such a thing as "rewiring a brain" and a way to increase your productivity. This is coming from someone who all throughout grade 1-12 had exceptional results in school but has resulted to pmo and binge eating to make up for stress and decreased academic performance for the past year and a bit (in my second year of university studying computer engineering with goals to get a phd in AI) to the point where its done multiple times a day. For example, if I ever sit down to work on some programming assignments I just quit after a while and result in relapsing and wasting time. I'm not sure if its even reasonable to blame this on pmo (however upon some google search I found people like Newton, Warhol, Tesla, Kant as well as other very notable figures were extremely chaste and even died virgins making me link pmo to a lack of mental clarity and desire. motivation to do things daily). any of you guys have any advice or personal experience from pmo?
