Again, I don’t belong in my own home

I wish I was dead.  My little sister told her son she’s not buying any more milk, because I drink it all up too fast.  I’m getting awfully tired of this, "You can’t talk about me behind my back, but I can do it to you" attitude.  I think I may be asking them to leave soon.  They use OUR food money on whatever they see fit, whether they get anything WE ask about or not, taking advantage of my social phobia, but then, my own sister has the gall to complain that I drink too much milk?  What about the FOOD I’m NOT eating, out of concern that our six-person household won’t have enough to last?!  

Never does anyone point out a good trait..  Only the bad.  Apparently, I’m such a rotten, stinking person that it’s all anyone can ever notice.
