God gave us free will to Choose, there are always going to be times of uncertainty in life for that reason. All you can do is pray for clarity, but sometimes God doesn’t always tell you “Do this , then this next then this next” he sometimes points you in a direction and let’s you figure it out. Just as a baby learning to walk cannot have it’s parents say " put the this leg in front , not this leg, now the right leg again" e.t.c
The parent , instead gives the Baby support and something to aim for while it figures out the physicality of walking by itself, and “deciding” what to do with its’ legs
You can’t expect God to tell you every single direction and choice to make, which some people do expect, even I myself have been guilty of this in the past until I realised a few things. You, have to also, make effort to make your own choices, and hopefully and faithfully they will be the right ones sometimes not, that’s part of learning. Other times it will be as clear as day, what you must do, and again you can choose that or something else.
I wouldn’t get too anxious about these things as it only adds to the uncertainty and you could spend a lifetime worrying about things you cannot change anyway. Just pray and ask God for direction and try to make the best decisons you can, for God for the greater good and for the life God wants you to live. You can also discuss things with a priest and seek some spiritual direction about big decisions , or any choices you’ve made which worry you. But for the most part, when you are strong in faith and prayer, you often find the right decisions are glaringly obvious to you and they are not always what you would expect and God is not always standing their with a huge Megaphone, shouting you on like those guys who row boats in the Olympic games have. Sometimes he just silently points you where to go, and you must follow , often not knowing where the path leads.
Hope that helps
God Bless
