Soul Traveler

"A Soul lives in a Cursed body and has 6 weeks to jump to a new body to avoid Death"

I have been Cursed. How did this Happen? I am still me but in this new body. I want to Live, but my time will Run out. I have just six Weeks, and I must travel to a New body. But to do this, I must Kill Another. Can I do this? Or will my time expire?
