My sister and I were talking about something and she brought up some conspiracies she was scared about. I wasn’t being condescending in any way and just showed her something debunking what she was scared of. Suddenly she went off on me, implying that I just think I’m better and right all the time and that I just want to prove people wrong. I just wanted to show her that she didn’t have to be scared about the things she told me because it was false info. 

Things escalated very quickly and she said some not nice things and this was not remotely how I intended our conversation to go. I’m trying hard not to get upset but it’s hard when I feel like there’s nothing I can say or do. I feel like whenever this happens, we can only become okay again on her terms and it’s unfair that she never takes accountability for the mean things she says. It’s always up to me to apologize and cater to her needs. 

What do I do in this situation? Do I just wait for her to come back around again? It’s taken months before and I always fear of something bad happening while we’re not on speaking terms.
