This is really a medical question and no one on these forums will be qualified to answer it. The most you can hope for is anecdotal comments regarding people's own experiences of being on citalopram and how they fared with coming off it. If they fared badly after withdrawal and continue to suffer, then it's not beyond the realms that it could be a mind/body/TMS response to the change, or it could be due to the after effects from drug withdrawal. As with any prescription medication going on citalopram is not without risk and coming off it won't be without risk either.
Perplexity.ai told me this, when I asked about symptoms after withdrawal:
"Some people report prolonged symptoms after citalopram withdrawal, but medical consensus views true long-term damage as rare, with most issues resolving over time through proper management.
Prevalence of Prolonged Symptoms
Around 40% experience symptoms for 6+ weeks and 25% for 12+ weeks post-tapering, often including fatigue, mood instability, anxiety, or sensory disturbances like brain zaps, especially after 5 years of use. These can mimic depression relapse, complicating diagnosis, but studies emphasize they're typically self-limiting rather than permanent.
Evidence on Long-Term Harm
Persistent post-withdrawal syndrome (PPWS) is debated; patient forums describe ongoing emotional blunting or dizziness months later, yet clinical reviews find no strong proof of irreversible brain changes from citalopram specifically, unlike shorter-half-life SSRIs. Risks rise with abrupt stops, but slow tapering reduces odds significantly.
Consult a GP (medical doctor) for monitoring when on citalopram and regarding and before and during tapering withdrawal."
