GET RICH OR DIE TRYIN' star Joy Bryant feels sure she'll never have a grittier film role than playing 50 CENT's girlfriend in his semi-autobiographical biopic - she almost had a breakdown on the set.

The sexy actress confronted the rapper, who she is reportedly now dating, about his life and how he kept his head - because she was losing hers as the depressing story unfolded.

The former model tells Complex magazine, "It was super-intense. I wanted to be the best I could be and damn, it was hard. I would do it again in a heartbeat though - if I had some Zoloft (antianxiety medication) and super-quadruple therapy.

There were times when I thought I would go off the deep end, become an E! TRUE HOLLYWOOD STORY (US TV show), run off to the mountains somewhere and be a hermit and write a manifesto."
