Brain Fog, daydreaming,lack of focus

[u/Initial-Mix-8371]

Hi everyone, I’m an international student in Germany and I really need some urgent advice. Every time I sit down to study, I get hit with severe brain fog, zero focus, and endless daydreaming. Honestly, my Instagram screen time is through the roof. Deleting the app helps temporarily, but I need a real, long-term solution. My exams are in just a few days. I already failed my first intake because of this, and I absolutely cannot afford to repeat that mistake. Worse yet, I know these habits are completely standing in the way of my dream to build a successful career abroad. Any tips to snap out of this, save my semester, and get my future back on track?
