Solved: I think the song is called "Stay" or "Stay With Me"

this song was late 80's/early 90's sang by a woman the only lyrics I remember are "Stay with Me." The woman had this haunting voice somewhat in the style of Amy Lee of Evanescence (when she sings high). I remember a few details of the video. The woman had long black hair and was dressed in black (I think) but she was leaning over someone's while crying and singing "stay with me." I want to say there may have been two women but I'm not sure.

Any leads would be greatly appreciated!
