Good and Evil?

Since I was a child I had two voices besides me in my head. I tried to talk to people about this but they just looked at me, maybe thinking I was making things up or something like that. In the beginning they were mostly quiet, only remarking on some thing or the other every now and then. I ignored them, mostly because I had nothing to say. But as time passed by they got more and more active and I begun to talk back.
         I even gave them names. Calvin was the first one, he seemed to be the sensible one and I usually agreed with him. The second voice I called Albert, he was more neutral and sometimes very hard to agree with. After I became a teenager, a major thing for me at the time, Calvin and Albert got even more active. They begun to tell me to do things, sometimes good things and sometimes bad things. Often it was hard to decide because they were always disagreeing. As time passed the arguing continued.
         Then one day, Calvin told Albert that he was getting tired of him and would make him stay quiet. I did not think much about it. But the next morning Albert was not there. I asked Calvin about it and he answered that we would not have to worry about him any more.
         All my life I had had two voices, but now I only had one. And I can not stop wondering, can I trust him?
