Wow, it is a powerful song, about what seems to me to be an unhealthy attachment. Is it BPD? I don't know. We do expect a lot from other people and get let down. Sometimes we really expect too much--like they can always be there for us, every second--and yes, die for us. Or that we would do anything for them---anything, even if they don't care for us.

Yes, I think it's growth that we recognize this kind of relationship as unhealthy.

My two cents' worth, anyway.

I'd have to listen to a lot more of his songs to see if I think he might have BPD, though.
