31-year-old Cassie Young was very excited to get engaged but soon after she posted a photo of her new ring on Facebook, she was contacted by a personal trainer who tried to fat shame her into using his services, however, Cassie wasn't having any of it. 

Our ten year anniversary is a heartbeat away but we just signed up for forever. 💍 Ps. I totally won #Cassopoly

The trainer, who she didn't name, did not take no for an answer when Cassie politely declined. Instead, he wrote to her, “I know you want to look your best on your wedding day. If you don’t hire me, hire someone. Those pictures last centuries. Your children’s children’s children will still have those pictures.”

Cassie explained to him that she will look her best because of how happy she is to wed the man she loves. She added, "I know it’s probably hard for you to understand this, but it’s taken me a long time to love my body. I’m constantly shamed or reminded that I’m heavy and I should be embarrassed — or people are embarrassed for me — or just straight up rude, calling me ‘disgusting.’ I’ve battled past all that and like myself and how I look.”

This is long, but I feel that it's really important. This guy reached out to me on Twitter with a pitch (which I have...

The exchange went on with the trainer stating Cassie can't be happy with the way she looks and that she is lying to herself. 

Young attempted to tell him that "pounds do not define you or your worth" and that he is a mean person for fat shaming, but it didn't seem like the trainer got the message. 

👈👈👈 HATERS TO THE LEFT. I’ll be honest, yesterday the trolls got to me for a hot minute. Their comments didn’t hurt my feelings so much as stole my faith in the world. I was shocked that people could be SO cruel and SO nasty, and I wondered why we should even bother about fighting against this cold, biter, heartless Army Of The Dead. . And then you reached out. And you. And you and you and you. You told me your stories of ordering your first two piece. Your battles with eating disorders and self-acceptance. The struggle with loss in your family and weight gain because of depression and how you battle it every day, head held high. Or going into the water in a bathing suit to play with your kids and make memories for the first time instead of hiding under a beach towel. Or stories of your kids, who see the world through innocent, honest eyes, and don’t get what the problem with being overweight is (because to them there is no problem.) Or the heartbreaking stories of how you or your daughters or sisters were on the precipice, and all they needed to realize was that fat is literally just an adjective, and not a judgment on who they are as a person, and now they’re getting married. . Thank you guys. You drowned out the trolls. You checked on me to make sure I was ok. You slammed the haters and showed me the light again. Texts, Tweets, Emails, DMs, Facebook Messages. There’s not even a comparison to the level of love I have seen on the internet from @TheBertShow community - my radio family - and from absolute strangers. . If you are struggling, know we are out there. Not only the outspoken protestors, but also the silent allies. We will stand tall with you and we will win this fight. I promise you. . EVERY body is beautiful. . This photo is for you, trolls. Eat your ❤️ out. . . . #EffYourBeautyStandards #EffYourBodyStandards #MYPerfectBody #LoveYourBody #IAmWhoIAm #HatersGonnaHate #BodyPositivity #LoseHateNotWeight #LoveYourself #BodyPositivity #EverybodyIsBeautiful #HealthIsWealth #SelfLove #HonorMyCurves #CelebrateMySize #TheRealMe #BBW #SelfAcceptance #RealBeauty #IAmGoodEnough #IAmWorthy #LookWhatYouMadeMeDo #AllTheHashtagsBecauseThisIsImportant 📷: @ownboudoir
