Lyrics Tides - Therapy?

I think my ship has sailed
I can't see tomorrow
What use will I be
If all I have is sorrow
These tides leaving me behind
Day by day by day
Your life ebbing out of mine
Wave by wave by wave
Standing over here
Waiting to be swallowed
Whatever's left me here
A darkness I must follow
These tides leaving me behind
Day by day by day
Your life ebbing out of mine
Wave by wave by wave
These tides leaving me behind
Day by day by day
Your life ebbing out of mine
Wave by wave by wave
Wave by wave
Wave by wave
Wave by wave
Wave by wave
