For me, in situations like this, the fear and anxiety comes from the part of my brain screaming, "but what if I can NEVER fix this?" Which is of course completely nonsense. There is ALWAYS a solution somewhere, even if it's VERY hard to find, or even if it's not the one you want.
My first serious job as an adult was avionics repair. I knew how to do SOME component-level troubleshooting but I wasn't very good at it and always got lost in schematics pretty quickly. When I ran across a broken device that had a problem I couldn't solve within 30 minutes of investigation, my first instinct was to say, "welp, this is beyond my abilities" and ship the card or box off as permanently broken, or try to pawn it off to a more senior tech in the shop.
Fortunately, I had a mentor who disabused me of that tendency. He taught me that EVERY fault has a cause. Every time you think you've exhausted all options, what it really means is that you've only exhausted all CONVENIENT options and you just have to suck it up and get cracking on the harder paths.
