RELAPSE (etymologically, "who falls again") occurs when a person is affected again by a condition that affected him, or her, in the past. This could be a medical or psychological condition such as depression, an eating disorder, schizophrenia, bipolar disorder, multiple sclerosis, cancer or an addiction to a drug and or substance abuse.

The sky's clear tonight
Even stars lost their light
Still I pray that you may find
The road back to my life
Half empty, half full
How can life be so cruel?
You left me alone
Yet I still wait for you to come home
Stuck in reverse
You're my sweetest curse
I close my eyes and go back in time
Reliving the days when your heart's still mine
