Literature and poetry have often described love as a kind of madness, and the medical profession takes a similar approach. According to the Hippocratic Medicine view, passionate love will almost always fade or turn into "love melancholy" — this is a form of depression or sadness. Passionate love is the love in the "honeymoon phase", the beginning of new love, but it burns itself out after a year or two, compassionate love is what occurs after passionate love fades, it is a stronger bond of companionship. In both cases, lovesickness can be experienced if love is lost or unrequited.
