Mood swings

My mother kept accusing me of something that I have not done. From young she always does that. Nowadays she kept repeating herself saying that I am irresponsible. She caused my father's death actually and still be happy about it. In the eyes of the world, what would people think ? To think she comes from Pentecost Methodist church which is so good in fellowshipping. To think that there is such thing as injustice.
