I agree with the other comments as well. I really think that someone he loved did pass away. When he says:
"When I wake up
All bottled up
A ray of sunshine tells me I am not alone"
Maybe "a ray of sunshine tells me I am not alone" means it's the person he loves looking down on him from heaven and she's trying to make her presence known by being the warmth or ray of sunshine that shines down on him in the morning. Maybe trying to say that even though she's not physically there with him he can still feel her. I don't know just a thought! Beautiful but sad song.
