I'm sad about wasting time at med school
What makes you think you wasted time at med school?
I was pushed to do med school by my mother, who's a doctor.
You should not think that it is a waste. Medical knowledge can be helpful in so many situations.
I agree but it just wasn't what I thought it would be. I'm already thinking of a way to drop out of med school.
Well you've come this far, it would be a waste to quit now.  Just because its not what you thought it would be doesn't mean you can't turn it into something more. You should think long and hard before making a decision to quit because you may not get an opportunity like this again.
