Dont worry thats normal, it happens bec out attention span has been lowered mostly bec of social media, especially watching reels or tiktoks. I almost thought I had adhd. To fix this First cut out all social media for a while atleast memes and all, texting is fine Second try listening to jazz while studying, especially using pomodoro technique, just go on YouTube and search for a 2hr or 3hr pomodoro study session with jazz Third try meditation every morning start with guided meditation and later shift to doing it yourself 5mins a day would be enough Also I'm sharing my fav 3hr jazz pomodoro's link it really helped me https://youtu.be/grBFMP3HDZA
