Didnt think it was going to happen to me

I ebf, baby is almost 9 months. This journey has been so easy and the last few days I've noticed my baby is losing weight and I can't pump or squeeze any milk out of my right side. Baby is crying at that boob too.

Having hubby get so many things from Target (mother's milk tea, cookies, coconut milk, and more)

I also realized I haven't been drinking as much water as I used to and even when I was drinking more water it still wasn't enough. I'm scared. The left boob still seems to be producing. I am just so not ready to end this journey and feel like a failure. Can't believe I wasnt paying attention. Really hope I can't get my supply back up
