My brother has mental illness and he lives in a home. He lives like a celibate but a home cares for him. I do not know if he could be a priest, but it is true that some mentally ill people live like celibates.
Celibacy (abstaining from marriage and sexual relations) in the religious sense is a vocation, a conscious choice in the service of God.
Your brother is in the care and supervision of people trained to look after mentally ill people. That, and the effects of his illness, make him unsuitable for the priesthood. Being celibate doesn't have anything to do with it. He probably has no choice but to be celibate, in his circumstances. He can't care for himself, much less make a living for a wife and family.
