Donald Glover, who left troubling notes on Instagram earlier this week, has offered explanation for his online rant. Speaking to PEOPLE on Wednesday, October 16, the "Community" star said, "That night, we had a show, and then afterwards, I had this moment of feeling like, 'What's the point? Why am I even here?' "

"I just wanted to write down my feelings. I definitely was just expressing myself," Glover added. He also insisted that he was not depressed. "If I'm depressed, everybody's depressed. I don't think those feelings are that different from what everybody's feeling. Most people just don't tell everybody," the actor/rapper said.

"I was just tired of telling people I was tired. It felt like every day someone would ask, 'What's wrong. Are you OK?' And I would say, 'I'm tired, I'm tired.' I didn't want to do that anymore. I guess sometimes not telling the truth is just as bad as telling a lie," Glover explained, adding, "I'm glad people saw it. I feel like I got some stuff out there. I got it off my chest. It felt like I had been holding on to something."

Glover addressed various issues in seven notes which he posted on Instagram on October 14. "I've been sick this year. This is the first time I've felt helpless," he wrote. Glover also said, "I feel like I'm letting everyone down. I'm afraid people hate who I really am. I'm afraid I hate who I really am. I'm afraid my parents won't live long enough to see my kids ... I'm scared [my girl's] still in love with that dude," among others. In the last post, he wrote, "I got really lost last year. But I can't be lonely tho. Cause we're all here. We're all stuck here."
