I would do this if I was you:
save at laest 1 savegame from your playthrough you have played a half year back (also if you go further with this).
Begin over again is a possibility if you wish to clear your mind about the Story

There is so much to discover in the Orobas Fjords and this game don't hold your hand, so I can understand you're confused now...
I would say you:
give your earlier playthrough at laest one big chance to survive

.. maybe you discover again what you forget?
