You told me that they can't understand the man I am
He thought that through his music he would be able to express who he really is and people would be able to understand him. A translation would be instead of saying “you told me that they can understand the man I am”, it would be “I told myself that people can understand me” and then he’s saying that people don’t understand who he truly is or wants to be because he’s had to look inside at who he really is and decide if he should change the way he does things or if he should just give up. If he wasn’t contemplating the decision he wouldn’t even have to question himself and this line wouldn’t be a part of the song.
