Did the three aforementioned divorces take place, which were issued in states of extreme anger and without full awareness or intent, knowing that one of them was uttered with the phrase "your divorce is on my tongue" followed by "you are divorced"?

The states of divorce in anger have been previously explained. As long as you have consulted the specialized scholars and they have issued a fatwa that your divorce did not occur due to the intensity of your anger, there is no reason for your confusion and doubt. Be reassured by what they have advised you, and do not pay attention to obsessions and doubts. Beware of yielding to whispers, seek help from Allah, and supplicate Him frequently.
