This song seems to have it's roots in Chris Cornell's past - his failed relationships, his battles with drug addictions, depresson and anorexia.
The chorous and the concept of the song seem to deal with the absence of love and happiness. He is saying that there is no such thing as feeling nothing. Since there is no such thing as nothing, there needs to be a feeling in life that replaces happiness when happiness is gone. For Cornell, these were feelings of depression and anguish. He has now reached the resolution that to save yourself in the absence of happiness you need to make the "choice of how you fill the hole".
