Losing weight/wedding vent.

I've always been bigger than my sister. She's been tall, skinny, and tan her whole life, and I've been the fat sister with the huge boobs. (I never wanted to lose weight, b/c I loved my boobs, and didn't want to lose them, lol) But after 3 kids, she's plumped out a little.
I've lost 40 pounds since July, and I'm getting close to the weight she is now,

She's getting married in January, I'm supposed to be her MOH, and she's threatening to take me out of the wedding if I don't stop losing weight.
This is complete bullsmurf.
I get that she doesn't want to be upstaged, (which I have no intention of doing), but I find it ridiculous what she's asking of me. I'm doing it to better my health, not to make her, or anyone else upset.
I have done everything I could to help her plan her wedding, and she's treating me like smurf, all because I want to be considered healthy on the BMI charts, and be smurfing healthy.
/vent.

She sounds lovely, lol

Have you offered to help her take off her weight? Maybe it could be something the two of you can bond over.

That's pretty smurfing ridiculous of selfish of her

That is smurfing rediculous!! I'm sorry mama idk what i'd do in that situation  

My sister isn't in my wedding party cos everyone always compares me to her   And she's a total bitch but mainly cos everyone in my family goes on about how it's sad I'm not as pretty as her.

I would tell her that you are losing weight to better your health and you would hope as your sister she would support you in that. And if she wants to join you in your weight loss journey, she is more than welcome

Yes, we started couch to 5K together, and she never finished. I did. Now, she's pissed about it. I've offered to go to her house, and do 30 Day Shred, or anything else she wanted to... she's always busy.

I'd tell her to shove it.

Brides are freaking nuts sometimes, and they need to realize the world doesn't revolve around them. She shouldn't tell you "you need to be unhealthy because I'm too insecure to have you healthy and possibly upstage me." That's complete BS. I can't stand women who go all bridezilla like that.

I have told her, but she told me that she 'already has the dress altered.'

There's plenty of time between now and January!

My sister cried because we were tanning together and i got tanner than her at her wedding and she cried to mom.

She was a bridesmaid in my wedding, and was a complete bitch. I've done everything she asked me to, spent any money on HER wedding that she's asked me to, and I get this smurf.
I'm sitting here crying, I'm so pissed.

I'm about to just tell her to take me out of it.
My health is more important than her selfishness.

Sounds like something mine would do.

This a million times. Smurf that.

At my wedding, I was 3 months PP and I was like 200+ lbs (and I'm short, too). My maid of honor was my tall, thin, gorgeous best friend. She looked way better than I did but people were still paying attention to me because it was my day.

Tell her to stop being smurfing bridezilla and shove it. If she can't accept that, then take yourself out of the wedding and continue to be healthy   When she sees how amazing you look at the wedding I bet she'll wish she worked out with you!

Exactly! Some people are just crazy. I really just can't even understand how people can be just total bitches about weddings.
