I deeeefinitely feel where you are coming from. i worked until end of november at a science camp but since them I have been unemployed!! busy with other things...but not nearly as busy as I was during undergrad and then working 60+ hours a week. I'm sure it doesnt look great that I have been unemployed, but I have been helping take care of my sick Grandpa and volunteering weekends here and there doing things I am interested in and trying to scrimp and save so my savings does not run out before I find a new job. I think you get so used to doing things all the time when you are in school and then when you finally have a somewhat 'normal' or slowed down pace of life you feel kind of useless, maybe even bored and find lots of ways to doubt yourself. I just keep my head up and know I am doing what my family needs me to do right now and tell myself this little break has been long overdue....and also...you are doing something constructive...trying to get into medical school!! : )
