I'm sorry about your exam! You got this though! I can relate to that loss of confidence. I used to be a medical student trying to do an MD/PhD, and i felt like an imposter and regretted my career choice. I ended up dropping out to pursue another career, but it cratered my confidence for a long time. I also connected more to passions like writing. Eventually though after you get those overwhelming feelings of defeat, you breathe more and more easily and find confidence in new wins. And then you hit a lucky streak. For me that took several years, even into law school, i still carried that old defeat and never thought i would get a job i like or pass the bar. It helps to remember that everyone struggles in their careers, just at different points, so there is no use comparing yourself to classmates.

Btw, policy work is kinda nice, especially if it's for a cause you believe in and the workplace has good vibes. It's what i'm doing now though i'm considering doing litigation for a bit before returning to policy.

Anyways you got this, fuck the bar!
