I really scared me

Tom,One of my roommate during the college came to this city I was living now. I invited all the other roomates here to get dinner together yesterday . Before John arrived I heard a sad news tabout him that he has been suffered from HBV for months ，God， On heard this news Bob was startled ,so did I.
Since the time John was suffered from HBV, I've been got dinner with him several times, I can understood the feeling of him,but I thought he had not to lie to me.He had konwn the danger we got dinner together,so he should told us the truth just for the friendship.
Though I was injected with HIBG, it was still scare me now. And I committed a mistake that, I should be responsible for the other roomates, All the other are innocent. so am I.
Neither would I wish John be impacted so much by the misfortune, nor I wish anyone be hurt by him.
I will go to hospital to examine wheaher the HIBG I was injected has been taken effect this weekend, God bless me.And God bless erveryone I knew.
