I don't know

You're my umbrella in the rain
And down it pours
A plaster for my sores
You get me up of my knees
You never expect a thank you or a please
You're my shore when my ship sails in
And when my sadness ends that where you begin
You give me light in the darkest of times
And when I can't see nothing you show me the signs
You're always there to show me which way to go
And where ide be without you
Well I don't know
