David Guetta - Without You Lyrics Meaning

Some of the lyrics just don't make sense for a love song.

I think its about heroin withdrawl:

I won't soar, I won't climb.

I lost my mind without you

I can't take one more sleepless night without you

I won't fly

I can't quit now

I will never be the same without you

If you're not here, I'm paralyzed without you.

Some of it just doesn't fit a love song. Also, check out Goo Goo Dolls - Iris because its about being an alcoholic.
