I think this song is about someone who is very special to him. The stars which he refers are the positives points of the person, as her character and values.
"But the stars that hang above you are too bright" - It's like the values of that person overshadows him, making him feel worthless.
"This life that is so precious is so cold / Your life that is so precious like the stars" - This life which he refers is a relationship between them, which is cold and dying by the differences, but he recognizes that the person will always be special regardless of everything.
