DEPRESSED & CURIOUS . That's what i'm having right now . I've done my best to be a good sister who you can share your problems with , talk about anything without any hesitation . And by trying to be not a perfect but almost , i hope that she can consider about me , have a little thought in her mind to care about me . But it seems like she'll never ever do it for the rest of her life . What is my fault actually ? I love her but with her ty manner driving me crazy until at a point i said 'just go away from my life , i don't need you' .  What to do ? :'(
