The "Modern Family" star covers the November issue of Seventeen, where she opens up about dealing with the negativity that comes with being on social media, attending UCLA next year and her very sexy high school graduation dress.
Though Winter has no problem posting whatever she wants on social media, sometimes the naysayers can get to her.
"It's definitely hard being self-conscious and having the world be able to tell you how they feel about you. Before Twitter and Instagram, if you felt a certain way about a person you didn't know, you couldn't tell them," she explains. "Now I wake up and I have tweets to me about how I'm a fat, ugly blah-blah."
"When I was younger, it took a lot more of a toll on me than it does now," she reveals. "Three or four years ago, I would have been devastated, like, 'Why do people feel this way about me?' I'm just being me. My sister helped me understand that people will say those things regardless of how you look. I tell myself every day, 'I look fabulous.'"
And it's those same haters who have motivated Winter to stay on social media regardless of what people say about her.

"I definitely have pushed myself to deal with the good and the bad because I feel there are so many girls who need to hear positivity," she confesses. "I feel like as many of us women who can band together and discuss things in a positive way will be so beneficial. Losing one person in that discussion wouldn't be helpful."
It's pretty clear Ariel has a good head on her shoulders, too -- she's attending UCLA next year!
"I'm ready to meet a more diverse group of kids from different backgrounds and different places, and I'm excited to learn and to be really responsible with my classes," she says of her higher education plans. "I think it will be great."
Though the 18-year-old actress got some flak for her super sexy high school graduation dress, she's standing by the look.
"I looked great in it, I loved it, and that's all that matters to me… There are so many other issues in the world that are more important than my graduation dress showing a little underboob," she explains.
