When you love someone, you can't not pretend not to see the bad things in the person you love; you see only the good. You will watch your loved person fall and fail, but you can't stop them and admit they're doing something wrong. I think Sia here may be singing about a man/woman she loves that was a drug addict with her. She sees him/her as he/she drinks and falls, but she'll always be there for him/her no matter what, but she will never be able to help this person because her love just makes her blind (''my love for you allows me not to judge the way you live'') and she can't admit that he/she should stop and fight for her/his life. Plus she still was a drug addict too, so it would be very difficult for her to tell the person she loves to stop, while she would continue to fall. And so they fall together...
This is just my interpretation of this beautiful song.
