Switching from breast to formula 😭

Unfortunately we’re having feeding issues and I don’t want my poor baby girl to be hungry if I’m not making enough so today we are switching her to gerber smooth formula. I really hate that I feel like I failed I really tried. She is 3 weeks old and latches on great I don’t know why my production is slowing down so much to where she’s not getting enough food but I have to do what’s best for her Anybody else go through this change and how did you deal with it emotionally I’m so upset with myself right now 😭😪
