I think the beginning, when he says, "Stand up straight at the foot of your love
I lift my shirt up" is about when he gets back home, he is presenting his real/old self. "Stand up straight", he faces it bravely, even though he's scared/nervous, because going back home can be hard. "At the foot", meaning he still feels like a child. "Of your love", he can be vulnerable because there is love and acceptance. "I lift my shirt up", he doesn't literally lift his shirt, it's saying he is exposed. Metaphorically naked around his family because they know him. He can't hide.
That's all I've got for the first part. I think most people who are talking about going home and the "buzz" that you get, whether good or bad, are basically correct.
