Does a divorce pronounced by the husband in a state of extreme anger, which caused him to lose consciousness and awareness and made him unable to recall anything that happened, take effect, especially since the wife has provided details of what transpired?

If the fatwa-issuing body in your country has ruled your divorce invalid due to extreme anger, you may act upon their fatwa. The spouses must live together amicably and cooperate in obedience to Allah. Explain to your wife that suicide is a major sin that no believer commits, and strive to avoid extreme anger, for the Prophet, peace be upon him, advised against anger.
