Jealous Guy, by John Lennon - I was dreaming of the past. And my heart was beating fast, I began to lose control, I began to lose control, I didn't mean to hurt you, I'm sorry that I made you cry, I didn't want to hurt you, I'm just a jealous guy, I was feeling insecure, You night not love me any more, I was shivering inside, I was shivering inside, I was trying to catch your eyes, Thought that you were trying to hide, I was swallowing my pain, I was swallowing my pain.

"Othello": O, beware, my lord, of jealousy; It is the green-ey'd monster which doth mock the meat it feeds on. Spoken by Iago (3.3.189-91)

So how does one go about letting go of all those jealous feelings? How do you forget the feeling of your heart being torn apart while you watch someone you love hold another person?
