Siblings caring for parents

My older brother. older sisiter and I (baby) shared in Mama's care. However, the older sister always saw herself has the instructor. Telling me what to do what not to do. She refused to let our dying mother have any sweets (which she enjoyed), my view was "Look she's 85 and her time is limited, she can have whatever she wants). So I'd sneak candy and ice cream in and Mama would smile and eat those treats like a kid. My sister would become enraged that her instructions were not followed and I couldnt have give a rat's batooty how mad she got.

After our mother died my sister accused me of saying something vert sinister in the siblings conversation with the minister (preparing for funeral). I never said what she claimed and knew I ahd not. I ask my brothers and even the minister if they remembered such a comment. All denied it ever being said. To this day my sister has had nothing else to do with me.

Seems she's always had some kind of underlying resentment towards me. Always.....and this isn;t the first time she's wrongly accussed me, but this is the first time it's hurt to my hearts core.
