Is it ok to not invite my sister?

I know the general rule is that it’s my wedding and I can choose who I invite. When it comes to siblings though, I’m unsure if choosing to not include her would cause me more anxiety than it’s worth.


We haven’t spoken in about 6 years. We lived in the same home for 2 years during that time and neither of us acknowledged each other. She stole several things that had sentimental value to me from my grandmother that had passed a year before, broke the zipper in my prom dress that I saved up to buy myself, stole clothes out of my closet when I was away at college. Then, she would play the victim and made our mom believe that I was in the wrong or gave her whatever it was that she had taken. After I moved out, our mom finally caught on to her and then she started telling the school counselor lies that could have gotten our brothers and her removed from the home. It’s a miracle my parents didn’t get a visit from CPS. The other important thing to note is that she and her half brother joined our family when I was 16 and they were 13 and 11 respectively, so she wasn’t in my life as kid. I still get incredibly anxious when I’m home for the holidays and she comes over, to the point that I have panic attacks, which is the last thing I want at my wedding.
My family would prefer I invite her, saying that she most likely wouldn’t bother showing up anyway. If I choose not to invite her or she doesn’t show up, I think I’ll end up having my extended family asking questions about where she is and why she didn’t attend. While answering these questions isn’t nearly as anxiety-inducing, I want the focus to be on my and my new husband’s marriage and us starting our lives together, not on why she isn’t there.
Is it worth the questions and uncomfortable explanations to not invite her? Or should I just hope I don’t have a panic attack if she shows up? I don’t really know what to do on this one.
