I’m sorry you’re feeling so bad, your symptoms are very similar to mine but for different reasons. I think you might need some more help from your doctor, medication withdrawal can be brutal for some people and can cause undo suffering. My symptoms are due to a covid infection two years ago and it’s been rough but now I feel like it’s easing up more and this is good. I also know how difficult it is to stop medication and deal with withdrawal symptoms, mine are due to benzodiazepines. I hope that you will start to feel better soon, it usually improves with time but if it doesn’t then you should see your doctor for help, best wishes.
