Ok, so...
I have kind of a constant battle going with my sister. Our whole lives, we've fought and it kills me. It used to be petty stuff, like I borrowed something without asking, or she ruined something of mine accidentally...but as we get older, it gets more serious.
The worst was a few years back, I went through some really hard times right after I left home, and I called on my sister to move to where I was to help me. I hardly ever ask for help, so it was pretty serious business. I was so grateful when she showed up. For about a week, things were great. Then she went behind my back and purposely befriended the very people that had hurt me, and started bringing them around me even though I'd asked her not to.
I tried to ignore it for a while, but obviously when she was flaunting these people in my face, it was hard. We got into a yelling match over it, and after that, she started calling our mom and lying to her about me-saying I was doing all kinds of stuff that I wasn't doing. It hurt me bad enough that I moved out and my sister and I didn't speak for over a year. I've been so angry at her ever since...and even though I forgave her and we talk now and are pretty close, the anger flares up sometimes. God has done so much for me, and I pray about this, but my human nature fights it...It takes a lot of effort sometimes to bite my tongue and not bring it up when I talk to her.
Anyway, my heart goes out to the rest of you that have posted, and I will keep you all in my prayers!
