I do not think you over reacted at all. She took advantage of you and ignored you for it. I'd limit my contact with her because I think she has been doing it all along ever so covertly...
My Sister Publicly Humiliated Me at Her Wedding—I Made Sure She Regretted It

Family relationships can be full of love, support, and shared memories — but they can also come with misunderstandings and hurt feelings. Weddings, in particular, can bring out strong emotions, since they are such important and stressful events for everyone involved. Sometimes, all the planning and excitement can leave someone feeling left out or unappreciated. Recently, one of our readers wrote to Bright Side to share a very personal story about just that.

Hi Bright Side,
My sister got married last month. I wasn’t just a bridesmaid — I spent 8 months helping her plan. I ran errands, put down deposits when she was too busy, and even paid a couple of her bills when she went over budget.
At the reception, in her thank-you toast, she mentioned everyone but me. She named her husband, his parents, their friends — even a cousin who came by once to fold napkins. She didn’t mention me at all.
I let it slide until later, when her husband joked that I was basically her “unpaid” wedding planner, and my sister giggled, saying, “Well yeah, that’s what sisters are for. Plus, she’s single with no kids! She had nothing better to do!”
That’s when I felt completely humiliated and unappreciated. I waited until she hosted her first big post-honeymoon dinner with both families present. I arrived with a large wrapped box and told her to open it in front of everyone.
Inside was a big shadow box frame displaying copies of every receipt, deposit slip, and to-do list I’d handled for the wedding — perfectly arranged with a gold plaque at the bottom that read: “In honor of the person who made it all possible.”

She froze as she saw it, her face draining as the table went quiet and then erupted into awkward laughter. I just smiled and said, “Thought I deserved a little recognition since your thank-you speech forgot.”
Now my family keeps blowing up my phone, telling me I ruined her first dinner in front of everyone and made it all about me. My sister says I’m being petty and swears she’ll never forgive me for humiliating her in front of her in-laws like that.
I can’t help wondering if I overreacted with my payback. Still, I feel like I had to stand up for myself after all the sacrifices I’ve made.
Sincerely,
Patricia
Thank you, Patricia, for sharing your story. To help you navigate this challenging situation with ease, we put together 4 pieces of advice.
The Power of a Private Conversation

She deserved to be humiliated! She purposely left you out of her speech then her and her husband had to twist the knife. They both know that you were taken advantage of and they both thought it was amusing and cute. It was not funny, it was disgusting.
Don’t ever set yourself on fire to keep someone else warm, you did god.
Ooh if one of my girls did this to their sister (I'm talking about not thanking her for planning the wedding) I'd personally have the others head. I'd probably loudly (after the speech) say what about your sister who did EVERYTHING?? As a mother I'd be furious!! Good for you for shaming her ungrateful butt!!
After being publicly humiliated by your ungrateful sister. Demand repayment for all you done. Then tell her that if her special day was ruined it was her doing. Remind that everyone, including you, have feelings too.
Absolutely ask for reimbursement for your cash outlay. Then she MIGHT gain half a clue as to your efforts $$$$
Spread it more in internet and public, if you recorded it, even better. Or you can have "calm talk" before you smash her life. If she shame you at public, then you have full right to do the same. An eye 👁️ for an eye 👁️, a teeth 🦷 for a teeth 🦷
Instead of letting the issue play out publicly, you might consider having a calm, private talk with your sister. Tell her exactly how much her toast and later comment hurt you, and explain how much work you put into making her wedding special. This gives her space to reflect without feeling publicly shamed.
A private heart-to-heart could open the door for a genuine apology and repair your relationship. It also keeps the focus on healing rather than escalating the family drama.
Lean Into Your Humor, Not Your Anger.
Your shadow box idea was creative, but it was fueled by hurt. Next time, you could use humor in a lighter, less confrontational way — maybe joking with your sister one-on-one about sending her an invoice or “charging by the hour.” This keeps the tone playful, but still communicates your feelings.
Sometimes humor is the best way to soften someone’s defenses and help them see where they went wrong. You’d still be standing up for yourself, but without creating a family rift.
Own Your Bold Moment, Then Move Forward.

You made a statement and forced everyone to see the effort you put in — and that’s not always a bad thing. Sometimes people need a wake-up call to recognize how much they rely on others.
That said, now that the message has been delivered, you can decide to move on without holding onto the anger. You can even tell your sister you didn’t mean to hurt her but needed to express how overlooked you felt. This approach allows you to keep your dignity while leaving the door open for future reconciliation.
Set Healthy Boundaries for the Future.
This situation shows that you were willing to give a lot — maybe too much — without clear expectations. In the future, make sure you set boundaries when someone asks for your time, money, or emotional energy. You can still be helpful, but decide what you’re comfortable with before saying yes.
This will keep resentment from building up. By taking care of yourself first, you’ll avoid feeling unappreciated again.
Recently, we heard from a reader who had a shocking moment happen right inside her house:

Comments
If your sister hadn't been so cruel and had acknowledged all the work you put in to begin with then she wouldn't be embarrassed. People would have already known all that you had done for her and she wouldn't have been made to look like she was taking credit for things that she didn't do. You didn't embarrass her she embarrassed herself by being dishonest and rude. You didn't say anything at the wedding which was her day. Any occasion after that is not hers. A family dinner is a family dinner whether she hosted it or not. Meaning you were just important as any other guest there and had the right to make sure people knew all the sacrifices you were making for her that she was ignoring. And as for the she'll never forgive you part, that's cool let her stay angry. Then maybe she won't ask you to organize her anniversary parties or her baby shower or anything else in the future, without any credit. Sounds like a win. And while I was at it I'd make her pay me back for all the money I spent on her freaking wedding, especially since her husband publicly acknowledged you as the unpaid wedding planner, meaning they are well aware that they stiff you on any financial support of the assistance you gave them.
I understand that weddings can be stressful and busy, but still...all sis had to do was acknowledge OP's work with the wedding planning, even if she had forgotten to mention her publicly, like a monetary gift, a special piece of jewelry or something extravagant like a spa day or an expenses-paid vacation. But, the groom, then the bride, poured salt in OP's wound by saying she's "an unpaid wedding planner". So, OP is NTA, but the bride and groom are!
Many people will tell you family is family so let it slide. You didn't choose who would occupy the same womb before or after you. Toxic people also have relatives. She acted. You reacted. Her problem.
