I can see this being about someone in a long distance relationship who is struggling to cope with not seeing their loved one, and their loved one is always on their mind. He hopes that he'll get through it and they'll see each other again soon, 'Hope inside us taking flight.' But he feels alone and hopeless, and he's letting go of himself.
He's broken up with someone, and he's struggling to get over it, even thought he's trying to find new people. 'It's unexpected, but I'm going home by myself.' To me, that means he was expecting to find someone new but he's going home by himself because he can't face seeing other people while he still loves who he's broken up with.
To me, this song is about one of two things.

Just my interpretation though.
