Do you think my mom is a hippocrite?

my cousin is extremely bipolar/psychotic. He has a huge temper and flips out on me all of the time. I try to help him but im getting really fed up with his selfishness and his bad temper. I suffer from depression as well. My parents always force me to hang out with my cousin and tell me i have no sympathy and that i should be ashamed of my self. ... But whenever im having a bad day.. suffering from depression my mom tells me im ruining her life and that i need to move out. isnt this completely hippocritical. She is the least sympathetic person i know. Whenever someone dumps me or a guy hurts me she always tells me i need to move out because im ruining this family with my gloom... what do you think?
