Michelle Trachtenberg Opened Up About Childhood Trauma Before She Died

“So. It’s Valentine’s week. Back in my day all the kids had to write a bulls–t Valentine’s Day card to everyone in the class. I never got one on purpose, everyone got a Valentine card. No one ever gave me one and they thought I didn’t need the attention,” she explained in a February 13, 2020, Instagram post showing a photo of her as a child.

“The kids and staff all laughed and thought everyone else should get one, being an actress since I was 3, apparently I didn’t need one. No one gave a thought I was helping my family pay bills. I was just the girl on the TV, it was just that their kid wasn’t on TV,” Michelle continued.

“This is challenging for me to post as people always contact me on social media saying oh my brother my sister went to school with you, you were best friends! False. The kids were cruel. There is no need to harp on the past. But I still have scars from being thrown down stairs and slammed into lockers headfirst,” the former child star revealed.

“I write this to every child, teen, person, out there who is bullied. You are something. Do not put your value in someone else. Not letting them win, is your win,” Michelle added. She went on to thank a teacher who “let me eat lunch in her classroom so the kids wouldn’t throw out my food or throw their food at me.”
