JWEI'm+sick+of+the+life+you've+given+me.+All+I+want+is+to+be+free.

When Angelica Biel say's "I'm sick of the life you've given me. All I want is to be free.". She is talking about finally breaking away from the oppression she has been under. By "the life you've given me" she is referring to what the oppressor has made her life like. This "life" is all the lines previous to this one. While whe she say's "Al I want is to be free." She is saying she is ready to live her own life. Not the life that has been forced down upon her.
