My sister is getting into my nerves!

My sister is causing me a lot of emotional stress these days. Months ago, a real property belonging to my father was sold at good price. She pleaded to my father to give her a big amount to settle her loans. As a very loving man, my father gave her 1/3 of the sales proceeds while my brother and I got only 1/9 of it. I never complained; I tried to understand because she might be sued in court. I thought she will change. She didn't! She started getting loans again for a business she had been planning. The business has not started, and guess what - the money she loaned is all gone! These days, she's getting goods on credit, but when they fall due, she tells me to pay. My God! This is too much, and it's causing me so much emotional stress. Why emotional stress? They are pent-up feelings...I have so much anger inside, but then I can't shout at her, slap her, nor may be throw a glass of wine on her face. I'm dying to do these things, but I can't get myself to do it out of respect to her. She's older than I am, 20 years my senior. I hope, one day, she will change, stop her extravagance, stop doing charity which is beyond her means
(just to get honor), or may be I could already throw that glass of wine at her. What a stressor!
