Lots of good advice here already.

The truth is, life just knocked you down. It happens. It sucks.

But... That doesn't give you an excuse to stay down and quit. Stand up. Stand tall. Get back in the fight.

So you didn't get into med school -- that doesn't mean you don't know anything. You can do anything with that kind of knowledge and drive. Biologist, chemist, lab technician, food scientist, sports nutrition, teacher, forensics, environmental reclamation. I could go on.

Make a list. Make a plan. Make a backup plan. Get mad. Get pumped up. Get going.

You believed in Santa Claus for 10 years. You can believe in yourself for 10 seconds.
