I'm sad :(

I can not believe how one person can hate another so normally just because of a situation that could not be overcome will give you to hate someone in such a way that you do not want to see him for what he says or thinks so I feel right now hated by That person that I do not know why I do not know what circumstance, I do not know how not to think or do so that he does not tell me anything I feel so sad in this house I feel more alone than accompanied here
