Feeling overwhelmed! Need some guidance.

Slightly whiny post so apologies.

First off I love this game. The atmosphere is off the charts but I’m completely overwhelmed.

Still in medical. Just had my first game over. Didn't realise there wasn't an auto save. Whelp.

Also maybe it's just medical but the level feels pretty big. Almost to the point of being overwhelming! Does it stay like this through the game? How are you meant to keep track of everything lol.

Looks at the size of the map!

When I'm finished is that it with medical? Or does the game go full open world later on? I'm not sure I can cope keeping track.
