there was no publicly available information confirming that Joaquin Phoenix has a specific mental illness. If there have been any updates or disclosures regarding his mental health since then, I would not be aware of them.
It's essential to respect the privacy of individuals, including public figures, regarding their personal health information. Mental health conditions are private matters, and it's up to the individual whether they choose to share such information publicly. If there have been any recent announcements or disclosures about Joaquin Phoenix's mental health, I recommend referring to reputable news sources for accurate and up-to-date information.
