Hi Dear Practo User If I understand you correctly, you r doing constant re thinking , this a symptom of anxious or somatic preoccupation. This happens most commonly in anxiety disorder. I need to know little bit more about your mood. R you feeling anxious or sad. R u able concentrate on ur studies. R u able to enjoy things. What about your sleep n appetite. If all r affected , they you have mixed anxiety depression. Well what ever it , you should not be panic. It's treatable.
