Okay not to your extent but having been thrown into the deep end in a foreign country with zero survival skills I can relate. First yeah I don't think most people have this kind of trouble. The key I've found is to beeline towards the thing closest to instructions (written or verbal) you can find. While getting panicky probably isn't normal (no judgement though, fuck normalcy), not knowing how to do things is perfectly normal and there's 99.9% going to be someone or something easy to find for people who have no idea what they're doing. Well, in the developed world anyway, but you don't exactly give me "I'mma go to Mozambique" vibes so you should be fine. Anyway yeah, I for one can say that help desks and clear signage absolutely hard-carried me through my first (and second, and third...) time at the airport; just don't be afraid to ask for help and pay attention to signs and you'll be fine.
