A mother of five who was mocked for baring her post-pregnancy stomach penned an open letter on Facebook
in defense of her body and is now receiving overwhelming support.
Tanis Jex-Blake, 33, attempted to wear her first bikini in 13 years on Canada's Alberta Beach when a group of two guys and one girl laughed, pointed and pretended to kick her belly, which is covered in stretch marks.
"I'm sorry that my stomach isn't flat and tight," she wrote. "I'm not sorry that my body has housed, grown, protected, birthed and nurtured five fabulous, healthy, intelligent and wonderful human beings."
The Canadian resident says she forced herself to stay strong in front of the ridiculers but broke down in her car on the way home – though their words could not fully break her.
"I'll have you know that as I looked at your 'perfect' young bodies, I could only think to myself, 'What great and amazing feat has your body done?' "
Jex-Blake would also like them to know she is not embarrassed about her 125-lb. body.
"I can only hope that one day you'll realize that my battle scars are something to be proud of, not ashamed of," she wrote.
