Hi, from what you have written it is difficult to come to any conclusion. It seems that you may be having stress of exams or some other stress and you are probably reacting to that stress with unwanted thoughts. Also, is there any history of substance use? You are taking some supplement, please check if they contain steroids. Please consult a Psychiatrist in person, a detailed evaluation will help reach a diagnosis and then a treatment plan can be worked out. In the meantime, try and exercise daily, eat healthy, try to get 8 hours of sleep, keep yourself busy and happy. You can do Yoga or simple breathing techniques to rid yourself of stress. Hope this helps, All the Best!
