Try a a kinder environment (at a smaller company) where your skills can grow. Also maybe a mentor.
This reminds me of a quote about how MIT has a way of turning physicists into lawyers. What it means is that people who started school trying to be physicists, got overwhelmed with competition at MIT and end up reverting to law school after graduation because their confidence in physics was diminished. Where if they went to a regular school, their skills (and confidence) would have grown.
Can't agree more. I've had similar experiences in a competitive environment with bad management. I moved from a small consulting firm where I was top performing and very happy, to a large hierarchical / competitive office where I lost a lot of confidence. Eventually I left and found a new job in a much better team and it made a world of difference.
Smaller companies are not a magic bullet for being kinder. They are often under pressure to deliver stuff to customers to crazy deadlines, grow the revenue every year by massive amounts, of both. They are less likely to be able to offer options vs. large companies where you can move teams but stay at the company. Smaller companies are great, I like working for them, but there is no guarantee that just going to a smaller company will be a kinder environment.
Odd comment because 'hack it' has multiple dimensions.
If you can't 'hack' physics (I correlate this with very high IQ, stoic commitment to research) it doesn't mean you'd hack medicine (Which needs decent IQ, amazing memory/recall and very good interpersonal and communication skills, and ability to handle stress, blood and dead bodies).
Oh, it's definitely not the case anymore. Anecdotes about students in competitive disciplines falling back on medicine are usually multiple decades old.
Today, there's no such thing as medicine-as-a-fallback. If you aren't solidly and deliberately premed for several years, building relationships with people who can write strong LORs, doing and documenting volunteering hours, and getting everything else in order, you don't stand a chance at admission to a competitive school.
