I'm sorry to hear that you are stressed but much like LLTQ a lot of this game is trying stuff and failing but seeing what skills would pass the checks and figuring out how to get them the next time.
I think one thing LLTQ did a little better is telling you the week before when something was going to happen a little so you could prepare a bit more.
You will have to brute force some of the early game but as a hint you can avoid most dangerous encounters via having high social stats much like you could in LLTQ. Which should help you to feel a little less stressed about what to learn. High Rhetoric, Etiquette, Empathy and Allure will get you most of what you need without too much effort.
Have a notebook handy as you play jot down the Turn number of certain encounters and what checks you need to pass then on subsequent playthroughs see if you can get there in time.
