i heard that this song is about how amy knew that people were going to judge her/the band about the new album and how it's different than fallen. 'i won't be held down by who i used to be', i.e. musicians can't keep writing the same music over and over, and as she changed as a person the way she wanted her music to sound changed too. i think the 'if you love me then let go of me' part means if you liked my past stuff get over the fact that my newer music might sound different and enjoy how my writing has grown. the weight of the world is being pressured by people's expectations to write the same type of stuff as she did before versus what she wants to write.
