Back in February, G Herbo dropped his studio album PTSD. The Chicago rapper named his album after the condition to "spread awareness" about mental health.
"It’s me spreading awareness to mental health, to PTSD," he told Complex. "I’m a product of poverty-stricken neighborhoods, like I come from one of the worst neighborhoods in Chicago … We don’t really understand, you know. And I was one of those guys. I was clinically diagnosed with PTSD through my therapist, and until I was aware of these situations, it was just normal."
