Frustrating siblings... Sounds like my que to join in...

I currently live with my 3 youngest siblings... I have no problems with my youngest brother, but the older brother and my younger sister are a hassle to me everyday... My one brother, who is 16 is, well, one of my best friends, I can tell him anything. The other brother, who is 18, has tuerettes, Asperger Syndrome, and ADHD... My sister, who is 11, is Bipolar, R.A.D and ADHD... I, myself, have Bipolar, R.A.D and ADD... It's hard to live in a house with so many kids with disorders that we often clash... My sister, just the other day, decided to throw a fit while I was babysitting her, when I tried to restrain her from hurting herself or others she proceeded to kick me in my bad knee, knee me in the crotch and tell me I was a retard and she f**king hated me... I have never felt SO horrible in my whole entire life about something someone said to me, like, ever...

I don't know... I really just needed to vent... Anyone have any suggestions as to what might help me deal better with my other 2 siblings while we are all three having a specific disorder?
