Yes!
I grew up saying I wanted to be a doctor. It was cute when I was little, but as I got older I continued to say so. I would watch surgeries on TV instead of cartoons like most eight year olds. I'd play with my microscope examining everything I could stick on a slide.
One day, when I was 11, I woke up and went into the kitchen as usual. Police officers were swarming the place. I remember an officer giving me a strange look. I now realize that he was saddened.
Dad sent my little brother and I over to a neighbor's house. I still remember one of the kids we regularly hung out with saying, "It's not fair. You don't have to go to school today." His mother hurried him out the door.
My dad called me over to the house later that day and sat me down. He told me my mother had passed away that night. Later, I learned she had become addicted and abused controlled substances used to put patients under in the OR (she was a CRNA). Phentonyl and Suphentonyl (I don't remember how to spell it). She made a critical error in the dosages and went face forward into the bathtub and drowned.
To me, my mother was as solid as a rock. And I thought that if she could succumb, then so could I. So, I cast my dreams of becoming a doctor, fearing the same thing would happen to me.
I attempted an animal science degree with aspirations of becoming a vet (reasoning that the drugs would be different and it'd still be the problem solving and scientific), but it wasn't the same. My attempts weren't even half hearted and my grades were proof. My grades had me on probation which still didn't motivate me. I quit school.
I was truly lost and wondered what I'd do with my life. I settled on working and putting my husband through school while I figured it out.
As I matured and learned that life is about choices, I realized that I could make the choice to walk a different path than my mother. I realized that this would give me a healthy respect of the medications used. I considered nursing (mostly because of my grades), but knew I wanted to be the problem solver. And then I decided to take a stab at medical school.
I'm chugging away at this undergrad stuff. It was a huge weight lifted when I started following my dreams and am truly happy.
Good luck. And never, never, ever, never quit.
