Do you know this song? - 1960's female artist

Hi. I've been searching for a song.

Female artist, and I'm pretty sure it dates from the early 1960's. One line in the song goes something like this:

"Just like the tide, you're changing"

Possibly a petula clark song but I've not found a match yet. (It isn't 'SAILOR')
Any ideas?

Thanks

It's a Brenda Lee songcalled Losing You:

Don't sigh a sigh for me
Don't ever cry for me
This is goodbye from me
I know we're through I'm losing you

Love sung it's song for me
Then things went wrong for me
Nights are too long for me
Because I'm losing you

Our love and our devotion
Were deep as any ocean
Then one day like the tide
You began to change
And you became a perfect stranger

Someone is holding you
Sharing the lips I knew
I can't believe it's true
That I am losing you

I can't believe it's true
That I am losing you

Y E S !!

Thank you so much Rayoj, I could kiss you
Finding this song was becoming an obsession with me and all my searches were coming up empty.
