Jolene by Dolly Parton tells the story of a woman feeling threatened by another woman's interest in her man. She pleads with this beautiful woman, "please don't take him just because you can" - she's clearly very insecure!
You're someone who constantly struggles with feelings of insecurity and vulnerability, and you worry about everything in life. In fact, you worry if you're not worrying about something. Listen up, recognizing your vulnerability makes you beautiful - unlike Jolene and the pathetic man in the story!
