Meh, I'm technically out of Sciforums, but since I checked out this forum to see what's happening... and since I think you have a serious problem... and I have close experience with this... It looks like a classic multi-personality disorder. The other personality in most cases is very violent and evil. It thinks about doing great harm either to itself (most often) or to others. If not treated it can end in suicide, and frequently does. It may also be a sign of a developing schizophrenia. So you should consult a psychiatrist asap, because it is very, very important to start the treatment in early stages, or you may lose the person(ality) you love.
