I wonder if the realism itself makes a person sad.I have gone through very bad experiences in the hands of people who are supposed to be protecting me.That changed the way or I would like to say,those experiences made me very realistic.Then this realism about people ,incidents and experiences, specially when I am right about them,brings dysphoria or sadness.If I were in denial or in naive optimism ( They abused me because they loved me ) ,I don't know if I would be a happy person now.
