I'm a sad mama right now

I've battled supply issues from the beginning, and since returning to work three weeks ago it's just taken a nose dive. Plus, I think that since DS is now getting bottles during the day, he gets frustrated at my slow letdown and low flow so he cries and hits my chest when I try to nurse him.

I'm going to keep pumping and trying to nurse him, but I just don't have a lot of faith in my body, I guess. And I'm angry at it...I'm angry at my body and feel like it has failed me and my son. I know it's totally irrational, but that's how I feel right now. It's not at all about formula vs breastmilk, it's that I love that bonding time we have together that no one else has, and I feel like I'm going to lose that so much sooner than I was ready for. At this point, I'm praying we can still have one or two sessions a day.

I don't really know what the point is of this post, I guess maybe I'm hoping for some kind words or any advice on how to get through this. I've been taking fenugreek since he was 4 weeks old and drink a ton of water, so I don't think there's much I can do to boost my supply at this point, but any suggestions would be appreciated.
