To me it sounds like he is referring to his relationship with himself or his inner child. 'When you're down that's where you find yourself'. Most growth takes place from introspection. And true introspection for those with a core wound to the inner child can only see themselves when they are down. 'This kind of love is hard to find' seems to me talks about loving yourself. For those coming from emotional neglect, to love yourself is all that can make you feel. 'Then you'll find there's nothing else' When you're lost you need to find yourself' hiding behind the wall.

This is beautiful in a thousand ways.
