"You healed me...You killed me and I survived... But what can I do now that you're back?"

You changed my broken self into a brand new one. You were the only reason I could be happy once again. Just when I thought we could actually be together forever... You were gone. I tried so hard to find you these few years but my efforts were all futile...  My life when back to how it was before again, just when can I ever get to see you again? Right now, I see you with someone else showing affection towards them. I continued to stare with my clouded eyes and shattered heart... 

Should I just continue fighting this war or give up?
