Do the verses, supplications, and anthems mentioned in my question, which caused me to have obsessive-compulsive disorder about divorce, fall under the category of allusive divorce terms or not?

We ask Allah to grant you healing and well-being. We advise you to seek Allah's help and ask Him to remove this affliction. You should also perform ruqyah (Islamic exorcism). The situations you described have no bearing on divorce. The divorce pronounced by one suffering from waswas (obsessive doubts) with explicit wording is not valid. The certainty of a wife remaining under her husband's protection is not removed by doubts. Therefore, do not pay attention to any delusions or whisperings. The cure lies in completely ignoring them, for Satan wishes to corrupt your religion and make your life miserable. So, hold fast to Allah.
