Black Mirror: Bandersnatch actor Will Poulter has announced that he’s stepping away from Twitter to focus on his mental health.

Poulter, who plays Colin Ritman in the movie, explained in several posts that he struggled with the positive and negatives of social media and needed to take time away. “I don’t want to appear unappreciative of all the amazing support I have received online for which I am genuinely grateful,” Poulter said in his post. “This is not the end. Consider it an alternative path.”

Poulter didn’t say how long he was stepping away from social media, but fans on Twitter think it has something to do with him being bullied for his role in Bandersnatch.
