Antidepressants while breastfeeding?

I was on antidepressants prior to pregnancy and will need to restart them immediately upon my baby's arrival in a few weeks due to an increased risk of PPD. Does anyone have any experience with this? I'm so worried they could be harmful to baby but of course I trust the doctor to prescribe something safe. It would be very reassuring to hear other people's stories and what they've been prescribed, though 💕
