I have known my sister in law for 30 years. We have had a peaceful relationship all of these years. She is my husband's sister. The other day we had to say no to her about something that she wanted done. She became very agitated and angry. She made many slanderous remarks and accusations towards myself and my family. She unveiled quite a large amount of resentment and ill will towards all of us coming out of her like a deluge. I begged her to think about what she was saying and calm down, but she said she didn't care if she destroyed the relationship with her harsh words. I tried for a full hour to talk her out of it, all the while she kept it up saying every mean thing she could think of saying those were her feelings as if I should allow her to say anything she wanted because she felt them. I have never said a cross word to her in 30 years and I did not do then either. The next day she wanted to start right back up again. I did not allow her to rant at me because I learned from the day before that I could not help her feel better and it was only harming me. It was no use to try. Honestly I was too beat up from the day before to handle it. I told her that and I needed time to recuperate. At least she agreed to just leave me alone. I feel like the relationship is ruined. I have a sick feeling in the pit of my stomach. I have never seen her like this. I feel there is no end to the harm that can be done by her in this state. I am now losing sleep over it. I need to let go of all of those things she said to me. I need to get it all out of my heart but I cannot seem to do this by myself. I truly want to be a loving person but I cannot allow her to do that to me any more. I may have harmed by myself by trying to help her. Will you please pray for me that I can heal up and gain wisdom should I have to speak to her again? Thank you so much.
