I believe that this song encompasses the final acceptance that one is allowed to be happy. It's like the person singing it is realizing that they're okay, that they're good enough to be loved. "Am I Good Enough for you to love me too?" is like saying can this be real? In the past, it never worked out, but now it's almost too good to be true so just tell me is this for real?? It's like you've always been in need of real love and never got it, and now the light has shone through..or at least, you are hoping that is so. "I'm still waiting for the rain to fall, pouring life down on me..." is sortof awaiting what's to come. Ur hoping for that which is good, and you can hardly believe this new great person in ur life that's making you so happy. The fear of losing it is still there, though. Especially with the line "So take care of what you ask of me, cuz I can't say no." That's like binding yourself to this person and depending on his / her to make you happy, or to give you a sense of self-worth.
