Sure, I'll give you the same hint:
"Have you tried exploring outside the dacha yet? You'll probably get notified about your survivor almost getting lost.
I wonder if there's an item you can use that helps people find their way..."
Hope that helps!
The handbook (available to download from this page) has a full walkthrough if you still get stuck.
Ah, I see. Yes, there's a lot of trial and error involved! Probably more than I intended!
I didnt make it very clear but equipping the health pack recovers a little bit of health overnight. It allows a survivor to recover health without losing a turn by resting in the bed. So, you can gather supplies and recover health at the same time, for example.
