I have always been a carefree and easy going guy. I have never really been scared or nervous about anything. Even when I went in to take my MCAT, I was completely calm and I did fine. But now I don't know what's changed. I am an MS1 and before my first round of exams about a month ago, I started feeling a constant adrenaline rush that wouldn't cease, no matter what I did. I attributed it to being nervous about my first exams and thought it would go away afterwards. But as the weeks have dragged on, the adrenaline rush has gotten worse. I haven't been able to concentrate on my studies and I am falling way behind. It's gotten to the point where I had to leave class because I literally cannot breathe. I haven't been able to eat properly and I have lost a lot of weight. I haven't weighed this little since high school. I have no idea what is wrong with me. I have never felt this way before. And now I keep getting further behind and other little things are setting off these feelings. My best friend just got his MCAT scores back and it will be close if he gets into med school or not next year. My girlfriend just had an interview to get into med school here and it didn't go well. Now everything is building up and I don't know how to regain control of my life. I slept literally all afternoon yesterday and all night, probably a total of 15 hours. And all the while I just keep getting further and further behind. Maybe I am just needing to vent here, but I am so scared and I don't know what to do.
