If i dont get along with my family members as well as my parents ~~~,?

wouldnt you think it would be a good idea to just remove myself from the situation? heres what happened: im going on a three week vacation to florida,okay? now ive had a lot of stress built up in my system,and im very very short tempered,my father who is crippled by alzhiemers riffles through things and somehow either lost or threw away my pport! my trip is in jeopardy and im going to be out $ 200 dollars (the plane fare round trip) because my dad screwed me up.now he and i had a heated argument and i inadvertantly went for him.so my mother called my brother who went ballistic and threatened to call the cops and put me in jail! who the hell would put their own sister in jail???? two months ago my brother went for me and broke my finger because he hates my computer! really,i think hes the one whos nuts,not me.and i know what people are going to say and ill still think im right regardless.
