You should have just joined the work or gone to a new place or post. Leaving your bag on the train means: first, you are worried about losing your ability to survive (wallet, etc.). The second possible meaning is that you have lost your luggage.
When you get off the bus and see the house, it means that all your worries are unnecessary, because you see hope.
I don't know the answer because I don't know your recent situation. I hope I can help you.
