Lookinglassgirl has a point, but she is also missing a big one. The depression and burnout that can possibly lead to suicidal ideation or completion are not comparable in academia. In medicine and nursing it is the day to day struggle to help/cure those who have no hope of such and then watch them hour by hour suffer. Even when there is a "cure" the pain many patients endure on that path can be agonizing, physically and mentally. This includes the patient's family, as you take on their needs as well.

Social and dating woes are seem hardly significant in comparison to med school and I would think if salary was a big factor for you it should have been researched beforehand. If I printed my salary as a nurse from 26 years ago you would need an emesis basin. No one wants you to feel sorry--that's sympathy, but some empathy would be appropriate and welcome.
