This is such an underrated part of the experience.
I think we all felt that way. Is that worth the high cost of tuition? Debatable. We're just about all working though.
I was changing careers after a decade plus of low-level grunt IT jobs when I was capable of doing so much more. It took probably 3-5 years just to build my confidence enough to do the bootcamp -- I had developer friends who were telling me for years I was more than qualified and capable but I'd found it so hard just to start.
A huge part of the lack of confidence has to do with growing up always being poor. The idea of a stable, high-paying job that's rewarding is almost unimaginable from that position.
