Community star Donald Glover opened up about the reasons he's leaving the show this year in a series of Instagram posts.

Glover - who plays Troy Barnes on the NBC sitcom - is only appearing in five episodes of Community's upcoming fifth season. Though he did not give a reason for leaving the show originally, Glover posted a series of photos on Instagram Tuesday revealing his thought process behind quitting.

"I didn't leave Community to rap," Glover wrote, referring to his Childish Gambino rapping career. "I don't wanna rap. I wanted to be on my own. I've been sick this year. I've seen a bunch of people die this year. This is my first time I've felt helpless. But I'm not on that. Kept looking for something to be in with. Follow someone's blueprint. But you have to be on your own."

The actor was presumed to be leaving the series to pursue his rapping career under his alter ego Childish Gambino, but his notes seem to reflect otherwise. Regardless, he is still releasing his second studio album Because the Internet in December 2013.

Glover continued his thoughts in another note, revealing his fears going forward in his career and personal life.

"I'm afraid [Community creator] Dan Harmon hates me," he admitted. "I'm scared I won't know anything ever again. I'm scared I never knew anything. I'm afraid I'll regret this. I'm afraid this doesn't matter at all."

Though it has not been confirmed, it is expected that Glover will only appear in the first five episodes of Community's fifth season.

Community will air at some point in the 2013-2014 TV season on NBC, though a specific premiere date has not yet been scheduled.
