Donald Glover seems fearless when performing as rap alter ego Childish Gambino, but the same cannot be said for the rapper/actor himself. "I'm afraid of the future," Glover, 30, scribbled out in the first of several notes about fears, which he Instagrammed yesterday (Oct. 14).  

"I'm afraid my parents won't live long enough to see my kids. I'm afraid my show will fail. I'm scared my girl will get pregnant and not the exact time we want. I'm scared I'll never reach my potential. I'm afraid she's still in love with that dude."

Next, the talented star admitted insecurities about his craft, writing, "I feel like I'm letting everyone down," followed by, "I'm afraid I'm here for nothing," and "I'm scared I'll be Tyrese." 

The "Heartbeat" rapper vented over seven separate notes, one which aired the possible root of his frustrations. "The label doesn't want me to release in December cause its not a holiday record and I'm not a big artist," he continued, addressing rumors of his run on NBC's scripted comedy, Community. "I didn't leave Community to rap. 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 the 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."

Glover's busy schedule may be taking its toll. He recently inked a deal with FX to develop a scripted series on the Atlanta music industry.
