Guilty n sad for not breastfeeding

i was depressed when i bf baby. i wanted to stop but yet felt guilty. i felt baby could sense my unhappiness and felt even more guilty. now i feel that i was foolish back then. should stop earlier and not made myself so upset. do not need to worry about bonding. the bond has been there since baby was in the womb for 9 months. even though i went back to work and baby is taken care of by helper, my baby is super happy to see me when i knock off work. as he grows bigger, the bond is stronger
