In my first year of med school I ended a serious long distance relationship, lost my grandfather the day before a final, and my grandmother the day of an exam (I postponed that one...but took the final on time). Now that I'm a 2nd year life had slowed down a little bit until my mom was diagnosed with some potentially serious health problems.
I am pretty good (usually) at compartmentalizing my emotions and focusing on the task at hand, which got me through last year. If I have to, I give myself a time limit on moping for the day - and force myself to return to my To Do list after that time has passed. Most of my classmates would tell you that I seem "normal" and "calm" but my close friends would testify to the inner turmoil I've been experiencing recently. I've probably told 4 people total exactly what's going on in my life and they've been as supportive as their own busy schedules allow - which has really helped.
With that said - life doesn't wait for you to finish med school. As I always say, "If you want to make G-d laugh, make a plan" and as one SDNer has reminded me on more than one occasion, "Life is what happens when you are busy making other plans."
Each of the challenges I've encountered has made me a stronger person in the end, and I can only assume that this most recent development will have the same effect.
Noelle - sounds like you have a ton of challenges recently. Keep your chin up. This, too, shall pass!!!
