My sister is depressed and she's completely tearing my family apart. She doesn't even care about getting better - she refuses to ever talk to her therapist and fights my parents on taking her medication. I completely resent her for it, but my parents don't blame her for anything. I feel like such an awful person/sister for hating her so much for this, but i just can't help it. My parents completely ignore everything that i do unless its something bad, but my sister is praised endlessly for anything that she does. I am always always always so sad about everything, but i won't ever tell my parents because i don't want them to worry. When i'm eighteen, i don't want to ever see any of them again, and i feel so guilty about it.
