"Romantic breakups are an inevitable, if painful, part of living. Along with eliciting a wide range of emotions, including anger, sadness, and shame, a breakup can bring health problems as well. These could include insomnia, reduced immune functioning, depression, and even the temporary heart condition known as "broken heart syndrome." The severity of symptoms often depend on the strength of the relationship and how traumatic the breakup itself was.
