I never had a lot of faith in my dev competence to begin with.
It gets even worse on my current (and also first) job. So far I have been handed solo projects that I need to deliver in a small amount of time using tools I have no experience with. I have two other colleagues I can ask my questions, but they are too busy working on other projects they got handed. Which leaves me 80% of the time on my own.
The bright side of it is if I make it alive somehow, my resume will be diverse.
