Hi Seeker. I think you might be on to something when you say that you've always been told what to do and what to want. I also wonder if this might be anxiety (social anxiety). What would happen if you went to your class tomorrow and were honest? What if you said "I don't listen to music often at all, so this was hard for me to answer." I'm curious to know why you didn't tell your teacher that this is a hard question for you? He / she could give you a different question to answer or even modify the question to "when you do listen to music, what song w/ lyrics do you listen to? (doesn't have to be a favorite)" Regardless of how you handle it tomorrow, I am sure doing the song your friend told you about will be ok too, if that's what you're comfortable with. But clearly, internally, you're not ok with this.
I'm not really sure if it makes complete sense to me, mainly because I haven't experienced it recently. But that doesn't mean your struggle with this issue isn't real. I do remember being a young adult and being VERY passive in my communication with others. I put their thoughts, needs, and desires before mine. Could that be what you may be dealing with? Does anything I'm saying strike a chord with you?
