Hailey Bieber is revealing why she deactivated her Twitter account last summer, and her explanation is actually pretty straightforward. Simply put, the model turned YouTuber can only handle so much negativity. 

On her latest vlog, the 24-year-old wife of Justin Bieber told psychologist Jessica Clemons, "I think when you're going through a situation where you just have so many people hounding you with the same thing over and over and over again, it starts to mess with your mind and then you start to question everything and you're like, 'Is there something that I'm not seeing that they see... Maybe they're right?'"
