Vincent, taking anti-depressants and receiving help from a clinical psychologist, said he believed he had been suffering from the illness for some time before he was diagnosed last December.
"For as long as I can remember, I've been riddled with self-doubt, I've had no self-belief, and I've just been hating the guy I've seen in the mirror," he told New Zealand's Sunday Star Times.
"I remember so many days that should have been great days, when I've gone home, slumped over a chair and thought, 'I just hate this and I hate myself.' I was completely beaten by it, I let it get to me and it just took over. Until you have been through it, you can't imagine how bad it is."
Vincent, 29, pulled out of all cricket before Christmas quoting exhaustion but has since returned to domestic action with Auckland.
Earlier English opener Marcus Trescothick and Aussie speedster Shaun Tait pulled themselves out from all forms of the sport citing stress-related illness.
