This song, as with every other song on the album is about heroin addiction and the lows that come with it. Even if you survive from the use of drugs, you will always have to bear the bad memories and know that you caused pain and sorrow to your friends and family. "Tomorrow you'll have to cross bridges that you burned today" says that what you did today will negatively affect what you can do tomorrow. It's a cryout for help, even though you know no one is going to help you and if you continue down that path you will die.
