To me this is about how day to day living can get really hard when you go through certain things, here it seems like she is talking about her parents divorce and her ED; but it could be interpreted with many things, and how they can effect other parts of your life. Things that should be easy become so difficult. 'Better than nothing' is maybe a very small piece of optimism, telling yourself at least you're still able to feel something.
