Necesito ayuda para traducir una cancion.

I have translated this song but I am not sure I translated correctly. So, maybe, someone will correct my mistakes.

De Porque Te estoy queriendo because I want you
no me pidas la razon - do not ask the reason
pues yo misma no me entiendo – and I myself do not understand
con mi propio corazon – my proper sweetheart, lovely or boyfriend - which is right to use?
Al llegar la madrugada – I arrive in the morning
mi cancion desesperada – my song is despairing,
te dara la explicación – and I will give you explanation
Te quiero vida mia, - I want you my life
te quiero noche y dia – I want you at nights and days
no he querido nunca asi.- I have never wanted so
Te quiero con ternura, - I want you with tenderness
con miedo, con locura, - with fear, with craziness
solo vivo para ti. – Only live for your’s sake.
