I Enjoy Being a Girl?

I began my 3rd year rotations this week. Quite frankly, I don't know if I have ever felt so lost/confused/dumb in my life. Needless to say, it has been humbling. If you watch any of the doctor shows, you are familiar with bedside rounds. It is where we do all of the research on a patient and discuss the patient in front of them and in front of med students/residents/attending doctor. Well, I am not very good at presenting because I haven't done it much. The doctor just started ripping my presentation apart in front of everyone. He interrupted me 5-6 times to tell me what I was doing wrong, and by that time, I was so flustered I could barely speak. I felt the tears coming, and I bit my lip as hard as I could while in the room. However, as soon as we walked out, the tears began flowing. Three of the people on our team are guys (including the attending doctor) and they all kind of just circled me and looked at me confused as to what they should do. I finally, said, "All right, we can walk now. I am fine." I was so embarrassed and annoyed, and I couldn't stop crying for some time! Now, I know I am portraying the doctor as a big jerk, but he is not. He was trying to help me with my presentation skills, but it was just all a bit much. I felt like the biggest wimp. So, if any of you girls out there have a secret to not crying, let me know! Obviously, the biting my lip thing is no longer working.
