Do allusive divorce pronouncements, uttered without intention and while suffering from obsessive-compulsive disorder and depression, take effect, especially with the inability to recall the intention at the time of utterance or to ascertain it now? And do abundant doubts carry any weight?

What you mentioned about not knowing your intention confirms that you did not intend divorce, for intention is purpose and will. Everything that happened to you does not necessitate a divorce from your part, because a person afflicted by obsessive-compulsive disorder is not bound by divorce while in the state of his obsessions. You must disregard the whispers of Satan. We advise you to consult a psychiatrist.
