Mine is a long story dear friend.
My citalopram days started in 2006 when I had a near fatal car accident. I recovered from the PTSD after about 18 months, but the doctor told me to stay on the Citalopram... his words were, you wouldn't take insulin away from a diabetic. Utter nonsense, but at the time I knew no better. This is what reps tell doctors to keep the money coming in to the big pharma.
When I realised what had happened, I went to the doctor (in 2016) who told me to drop (from 30mg) to 20mg for one week, 10mg the next and stop. Bad move! Took me from a position of being a very positive guy with his own company to a complete wreck. I then decided to learn more myself. This doctor was an idiot.
I tried cymbalta when I thought I needed a change of drug (as I initially went back on the 30mg Citalopram once I realise what had happened). But a lot of bad life circumstances had happened which was causing my stress, depression and anxiety. When nothing else worked, I simply thought that my system was fine when on Citalopram, so that can be replicated. So that is why I went back, and I did recover. I was going to start a withdrawal just before the covid kicked off, so that put pay to that, so I am still on my 30mg dose. But once I switched back, it took around 6 months along with an angel of a therapist to see real improvements.
But I had the brainfog the same as you, headaches, dizziness, weakness... you name it. It is all documented here on the forum. Just like Hat, I have been here through it all. Hat and I have seen some very dark days on this forum between us, but we are here - as much as everything else - to show people that it CAN be done. I never would have believed it, but I did it. It has changed my life for the better, and as crazy as it sounds, I wouldn't change it. It has given me a much clearer perspective, it has made me grow spiritually and has given me some of the best friends I will ever encounter in my life. My family here means the world to me, and I would do anything for them.
