Female, deep voice - rock

There was a song I heard on the radio last night, and now I can't remember what it was. It was a female singer with a deep voice, though she went high a few times for effect. It was a slow rock type song I believe, but I'm bad with genres anyway. It seemed like it was 80's or 90's, but that could be wrong as well.

Lyrics that I can remember had something to do with crying at night but getting better.

Sorry for the lack of information.

Wow, not a lot to go on... Let's first try to narrow the potential lists of artists.

Does the artist remind you of someone like Melissa Etheridge ("Come to My Window") or k.d. lang ("Constant Craving")?

Robin Beck?
Kim Carnes?
Stevie Nicks?
The Wilson sisters? (aka Heart)
