Ok that's why I asked. Maybe this won't be for me because I can't stomach much with operations. I want to study mental illnesses and help people with them. What do you mean by "holding traction"?
Are these rotations in your 3rd and 4th year of med school? What about when you do your residency? Are you then focused solely on psychiatry?
3rd year of medical school usually requires rotations in Family Medicine, Psych, Internal Med, Surgery, Ob/gyn and Peds. These rotations are usually 4-12 weeks long, depending upon your school. Internal med and surg are usually the longer rotations. 4th year you will be required to do a Sub-Internship, usually in the specialty of your choice, but since Sub-Is are not offered in every specialty, you might have to do one in Internal Med or Surg. You're also generally required to do a rotation in a critical care area (ICU, CCU, MICU, SICU, EM, etc). Some schools require Neurology.
Remember, the first 2 years are not totally benign if you're grossed out easily. You will have to take anatomy and dissect a cadaver. You will also likely have to look at lots of organs in pathology. Our school requires us to attend at least one autopsy during path as well. However, I think after the initial shock, students tend to adapt fairly quickly, or have no problems with it in the first place.
I guess the question you should ask yourself is what your goals are. If you want to work with and treat the mentally ill medically (as in, with medications), you will need an MD or DO. However, a PsychD or PhD in Clinical Psychology is an option if you are more interested in the different types of therapy. I would suggest you further research the differences between the two and decide which is best for you. I honestly don't know much about what you can and can't do with the other degrees. I would say that if you really want to be a Psychiatrist, and not a Psychologist, 12 weeks of surgery is a small price to pay. You'll get through it. There are plenty of students who are in medical school who do not want to do surgery. However, if you would be just as happy as a Psychologist, and think you would like that training more, that may be a better route. Good luck.
