I think that this song is about a young couple who is 21 (We won't be 21 again)
And they have been doing drugs and a lot of alcohol (you won't find love at the bottom, of a class c hole.The drugs would only hide it)
Then one of them dies from an overdose maybe and the other one is left alone. (You don't know what you got until it's gone, and you don't know who to love until your lost) Then the alive one finds a new partner and they doesn't want to repeat what happened to the old one. (I wish you lived like you're made of glass)
