When things changed

I was 22.  My drug taking habits had made me worried. So I went to the Kings Cross STD centre. I had Heb B. Triple tests, and I was the unlucky 5%. No immunity.  I would die from Liver cancer by 40. For the next 7 years of tests every six months. That was my result. 
I’m 29. Already a life fulfilled. And the test comes back. Surface E enzyme negative. I’ve developed immunity. I no longer have a death sentence. How to live now?
