Sharing my dark side and dark incident again!!!!

I again exploded over actually nothing;my parents me and sister were having breakfast!!!!!!And my father's mood had been upset since yesterday!!!That really puts me off and makes me feel abnormal;he seemed to avoid me but was talking properly to my sister;
I just got mad at that behaviour and it started growing;and withing 5 minutes i had lost myself ,,,,went on saying bad things ,abusive things loudly to all of them except my sister;;;;

Later after 5 minutes whn I was alone in a room,I felt all drained,and sorry and gulity;;;;;i apologied to my sister;;;but do not why i do not want to go and apologize to my parents;;;
which normal and good human would ever think abusively about their parents;i do not thnkabuseiviley,,,,,,but i became verbaly abusive in total madness,,,,,,i am full of extreme guilt;;;;;;

i ahte myself,really......i try to move on in life happily...and this happens and i am back to the same state;;;;

my sister just came to visit us and because of me she is so sad.......i hate myself again....
