The perfect scar

I´m breeding a scar.My body against it´s growth ,beeing devoured from whithin.My time to live the time for the accomplishment.I must be the one to die soon.The law is clear and I´m alone.By the end ,suddenly,I drain in another blood.I was not supposed to be careful so I let myself go.I don´t care for the oncoming,everything goes when you´re lost .Only one major eternal thing could beam my scanty life.Your sweetness.
