Hey,
Your story is good, however I am not entirely sure if it fits into physical journeys. My teacher had told me that a physical journey involves someone moving from place A to place B (whether he/she is moving countries or just going down to the shops is irrelevant), it should involve an obstacle (ie. character is moving countries, when he/she gets to the airport, he loses his passport) and the description of the outcome- what the character learns once he overcomes this obstacle (ie. broadens his/her appreciation of the world, learns more about himself etc). At the moment I would say that your story is more emotional journey or perhaps even an inner journey of how your character moves on emotionally after the death of her brother. I hope that helps.
PS. i may not be entirely right
