Most withdrawal symptoms after abruptly stopping Citalopram usually subside withing 3-6 weeks. Therefore if you are able to tolerate these withdrawal symptoms you can wait for few more days. These symptoms should subside shortly most probably.
If you think that these symptoms are persisting or increasing in severity, in that case, a possible strategy could be to restart 20 mg of Citalopram per day which will help in controlling these withdrawal symptoms. You can take 20 mg Citalopram for 5-7 days and then start tapering slowly by reducing 5 mg every 3-5 days till you are able to stop it completely.
In my view, second option is a better alternative, so just discuss with your GP about this strategy and hopefully you will start feeling better soon.
Please feel free to discuss further if you have any doubt or queries.
