Medication and wanting to breast feed in the future..

Holly👶🏼👸🏼💗
So basically, once my baby is born I really want to breast feed, however my doctor wants to put my back onto antidepressants once I've gave birth as he thinks I'm still definitely going to need them. I know you can't breast feed while taking the tablets, I'm stuck in what to do? Advice or anything please ladies? Majorly appreciate!
