Hey, don't lose hope. I got prescribed and took 30 mg of Citalopram for about 10 years to treat general anxiety. At some point, I wanted to stop taking it because of the emotional numbness (and also because of a tendency toward mildly aggressive episodes).
I gradually reduced the dosage from 30 to 20 mg (over the time of 3 to 4 months), then down to 10 mg (for another 2–3 months), and then I finally reduced it to 5 mg (half a 10-mg tablet) over a period of 4–6 weeks. I told my doctor beforehand, they only told me that I should fade it out slowly. But please excuse me for not knowing the exact time frames of the tapering process any more. I took my time at the beginning of the tapering and moved more quickly toward the end.
During and afterwards I didn’t notice any severe side effects, aside from the fact that the recurring emotions really overwhelmed me at times. Not only that, but I would cry at the slightest hint of emotional and romantic scenes in movies and series, which lasted for about three months. Nowadays, I feel quite normal. I miss the slight comfort Citalopram gave me, but I have my feelings back, I feel more myself again. If a bit more anxiety is the price for that, then so be it.
