As someone who has been suffering from severe AD withdrawal for 4 years now I would say that you are not being unreasonable at all. I was prescribed the drugs in 2000 because I was anxious about picking a college major in the US and was told that I had a chemical imbalance so kept taking them for 19 years. Wanted to get pregnant and tapered over 5 months (from 20mg citalopram). No issues until I went from 5 to 0. Then all hell broke loose.
The first 4 months were an absolute nightmare that I could not have imagined in my worst nightmares - I couldn't sleep for more than 2 hrs a night and kept being jerked awake every 30 min or so. 4 years later can manage about 5 hrs a night uninterrupted sleep but still have wake up terrors every single day. Had intense nausea and dizziness. Ate pretty much only ginger cookies for the first 4 months. Had intense bursts of anger (I used to never get angry before), akathisia, would forget my words - had to take time off of work for months. Eventually reinstated 2.5mg and have been tapering since but very slowly - still on 0.43mg. The first year was still horrible but less so than the first 4 months and only this year have I been able to have a more or less normal life because I have stopped tapering. But still get weeks of intense fatigue out of nowhere (and it goes as away out of nowhere as well).
The crowd wisdom is that most people can taper (cut their dose) by 10% of their previous dose every 4 weeks but it has been much harder for me - I can do maybe 2-3 % a month and then take longer breaks.
I was super lucky that I saw a paper by Mark Horowitz, a doctor at UCL came around in the Lancet at the time when this first happened because I didn't have an idea what was happening to me - my GP said I was just anxious but this was a totally different beast. Here is Dr Horowitz's paper. GP's don't know and often disregard the patient experience. I had to take this paper to my GP (he then apologized - sadly he is retired now and they don't make GPs like they used to) https://markhorowitz.org/#:~:text=When%20I%20tried%20to%20come,dizziness%2C%20anxiety%20and%20low%20mood. Luckily he believed me and prescribed the liquid citalopram which allowed me to taper by small amounts. I am a medical professional (though not practicing at the moment) so he listened but I know lots of women who are not listened to and their withdrawal symptoms dismissed as anxiety etc. (the new word for hysteria).
I was also lucky to find this site: https://www.survivingantidepressants.org/ which has been around for over a decade and has the experience of lots of people with AD withdrawal. They were the ones that told me to reinstate - they have advisors with experience (which was a tremendous help) and which helped alleviate my symptoms.
Whatever you do, please do not skip doses or alternate days - i.e. take your dose one day and skip the next. Lots of clueless GPs give that advice which causes kindling and makes thing worse. https://www.survivingantidepressants.org/topic/27800-hypersensitivity-and-kindling/

Lots of people think that even if they are placebos they are OK but they are dangerous placebos - they increase suicidality in young people (see FDA Black Box warning), they cause sexual dysfunction. Citalopram causes prolonged QT syndrome which can cause sudden cardiac arrest (rare but happens) https://www.fda.gov/drugs/drug-safety-and-availability/fda-drug-safety-communication-revised-recommendations-celexa-citalopram-hydrobromide-related#:~:text=Citalopram%20causes%20dose%2Ddependent%20QT,and%20confer%20no%20additional%20benefit., they increase risk of heart disease and early death etc. There are better placebos out there - magnesium (citrate/glycinate) is amazing; When ADs are compared to exercise, ADs are no better etc etc.
You need to decide whether you want to come off of these antidepressants but if you do please taper VERY VERY slowly - over years so that you do not suffer the way I did. People who taper very slowly (10% of previous dose a month) can have uneventful tapers. Citalopram comes in a liquid which you can further dilute (note the liquid version is 25% more potent gram for gram - says so on the leaflet but you can miss it).
