Breastfeeding && Formula feeding

I really need some real life mama experience, plz don't judge me. My first daughter was exclusively breastfed for 13 months && while I enjoyed the bond i fell into depression && didn't wanna take meds while breastfeeding her so I toughed it out. I am currently 24 wks pregnant with another sweet baby girl, I am really considering formula feeding but I don't know anything about it. My biggest question is can you tell the difference, like have any of you breastfed one and formula fed the other && noticed any difference? May sound silly but I wanna be healthy but don't want to jeopardize her health, if that makes sense. Plz help this mommy out 😫😫
