'Enjoy your [new] drama-free life': Entitled sister quits the job her sister got her after only 2 days, sister cuts her from her life and blocks her from getting her W2 tax forms

Isn't it just a kick in the teeth when you really go out of your way to help someone and they aren't even grateful? Or worse, they totally take advantage of your kindness? That knife in your back feels even worse when it's from your own family. But, family drama is no mystery to the world and happens often. 

Take this woman, for example, who recently cut her own sister out of her life. Her sister was a struggling mother of three, so she went out of her way to help her as best as she could. She drove her anywhere she needed to go, gave her money when she needed it, and took care of their kids. She even welcomed them into her own family. However, her sister never seemed to be grateful. And the final straw that broke the camel's back was when her sister quit the job she got her after only working there for two days… TWO DAYS. That not only was a blow to her sister's generosity but also made her look bad as an employee. What's a sister to do after that? Is there any coming back from it? OP thinks not. What do you think? 

Here's another story of a woman who was pushed to her limit and had enough.
