Hallo roslily. Glad to hear from you.
You mentioned some queries about the safety of taking citalopram whilst bf. tiktok's advice excellent.
In addition and sorry if this blinds you with science but I looked up a couple of things that refer specifically to that medication

If you still have concerns about the medication, my (limited) understanding is that celexa is an SSRI and there are other SSRIs which may work just as well for you and which may be worth considering if you are worried. Perhaps you could discuss again with your GP?
A resource (of sorts) is the pharmacy of the Portland Hospital. You could call them and ask if they prescribe citalopram to mothers who are breastfeeding. (You do not need to be a patient). If yes, fine. If no, then ask what they do prescribe instead. This may then reassure you or give you enough information to go back to your GP with.
Thomas Hale's publication is considered fairly definitive on medications in pregnancy and bf. Not sure how easy it would be for you to access that. Maybe NCT or LLL counsellors?
Some breastmilk is better than none. Much better. For you and for baby. Many many babies do not get any breastmilk. I shall not comment on the MW in question. The others have already said exactly what needed to be said.
I also realise that just getting through the next feed/few hours/day may be proving difficult enough without perusing scientific journals or calling hospital pharmacies.
My aim is only to facilitate your access to resources if you want them.
Please know that I am hoping that things will get easier for you.
