feeling like a failure

Cynthia • 22 | girl mom 💕
my daughter turned 6 months on the 11th, and we have been breast feeding this whole time. all i wanted while i was pregnant with her was to breast feed, my first goal was 6 months, and now it's to a year... but i have a feeling i won't make it that far :(
i've always been a just enougher, pumping wise she would probably starve if i excusively pumped. i don't know what changed or happen, but now i'm not making enough milk at all. 
i'm going back to work too, and i know this won't last for us. i have some frozen milk for her, but it won't last us another 6 months. 
i just feel like such a failure. yeah, i know fed is best, but like i said this is all i wanted to do. i love the bond i've been able to share with her. i just want to cry because i won't have that same bond anymore.
