Love sucks!

Love plays devastation with your body chemistry, causing you to act as if an addict bent on scorching her next fix. Studies have found, for instance, that serotonin levels decrease by up to 40 percent in the newly smitten, causing some to show signs of obsessive-compulsive disorder, a condition associated with low serotonin –which is why you cant seem to get the other person out of your mind. Additionally, cortisol, a stress hormone linked with the fight-or-flight response, is released, so you’re constantly on high alert. Sounds familiar?
Research published in 2005 by a team that include Brown and Fisher found that people who had recently fallen in loved showed strong activity in the area of the brain that produces and receives dopamine. Gamblers and drug addicts experience similar dopamine activity. “You’re not supposed to be satisfied,” explains Helen Fisher, a professor of anthropology at Rutgers University in New Brunswick, New Jersey. “you’re supposed to be driven so that you can win the person and eventually stabilize your internal chemistry.”
When a relationship ends, you experience symptoms that are similar to an addict’s withdrawal. Your dopamine levels go down, so your mood suffers. Your serotonin levels remain low, so your obsessive-compulsive disorder symptoms may not go away. In response to these imbalances, some scientist believe, risk-taking tendencies go up. “When you can’t have someone but you’re not willing to accept, you try harder and become more extreme about it,” says Fisher. Paradoxically, she says, this compulsive behavior may help you move on faster: “Either you win the person back or you him away.”
