Regrets of not breastfeeding

Any mamas have regrets about not breastfeeding? My milk didn’t come in right away, it took about 3/4 days so i used formula, by the time my milk came in, i just chose to stick with formula because thats what she had been using and now i totally regret it. She is 6 months old now, and i just really wish i would’ve breastfed.

* I am in no way bashing formula feeding, i am just saying how i personally feel, and looking for other moms who have experienced that same feeling for support because i’ve really been beating myself up for it. *

Edit: My nurses actually pushed me to formula feed, they said my baby was not getting enough milk.
