Chris, It's very common for people who are coming off of psych drugs to be "diagnosed" as bipolar, when in actuality, it's just a withdrawal symptom. Psychiatrists will inevitably prescribe more drugs (what else do they do?) for nonexistent mental illnesses which are nothing but withdrawal symptoms, therefore, spiraling the person downward into increasingly worsening conditions. Many people report that after they are through withdrawal, the so-called bipolar symptoms disappear.
These so-called diagnoses are really just descriptors, labels that psychiatrists make up and then change, subjectively, as time goes on. There's nothing objective or scientific about it. The DSM is a joke...if you do research into how it came into being, you'll see what a laughable publication it is. Check this out:
Just a word of caution. Don't believe the bipolar diagnosis and the recommendation for additional drugs to fix a condition that is caused only by antidepressant or other psych drug withdrawal. In such situations, bipolar is a non-existent diagnosis with a so-called "remedy" that will cause only more harm. When it comes to withdrawal or psych drug adverse effects, psychiatrists are delusional and in denial and, therefore, chase shadows by unnecessary and harmful prescribing. Don't let your wife be yet another unsuspecting victim of their willful ignorance.
