Is there a medication that helps for heartbreak?

Awwww, no. Sorry.: This could be a hot song title! There are Drs who might evaluate you and offer short-term help if you are too overcome to take care of yourself. It would only take the edge off - not mend the break. Therapy might help you see what went wrong in a helpful way. Support groups can also let you know you're not alone. It will hurt, but most do get through it. Best!
