P.M.
*le S.*, yes, there are serious pluses to breastfeeding. Bonding, nourishment, convenience, less expense. All worth some regret.
But not worth beating yourself up over, sweetheart. I suspect this depression thing has been working at you for a long time, and your daughter may be picking up on your mood. Babies are sensitive, and will often notice a mom's feelings even when the mom is doing her darndest to buck up.
Will you please do a few things things for yourself and your daughter?
1. Keep trying to breastfeed – get professional advice if you can. Your milk supply may increase again. Keep snuggling your baby close to you. She needs that contact as badly as you do.
I traveled to the Middle East with my first husband when my daughter was 7 months old. Suffered from dysentery the entire 6 weeks, and my milk dried up. It was awful for me; I wanted so badly, like you, to keep nursing. But I did keep offering my breast, and my daughter did use me as a lovey, a pacifier. Even dry nursing was a source of contentment for her. I would have given anything to get my milk back, but few women were breastfeeding in those days, and there were no lactation consultants. So it was what it was. I regretted the loss deeply, but that's not the same thing as what you're describing. I didn't hate what I had done to us, I just kept on mommying the very best I could, and it was good enough.
2. Keep working on that depression, and I don't mean keep working on deepening it. That will work against a secure bonding with your daughter, and kids who grow up with depressed moms often suffer for it later. Google this if you want to hear the studies. So if you feel helpless to turn it around without help, talk to your doctor. She/he will suggest steps you can take, medication and/or talk therapy. This is something you owe yourself and your child. Not getting help will really be letting her down.
3. You sound really, really low. Alcohol is known to deepen depressive thinking in many people. Please stop using it to patch up your feelings. It's not working. Honest.
4. The stories you're telling yourself are only making it all worse, too. Honest. Your thinking has turned you into a woman who has cheated herself and her child out of infancy's greatest joy, and your daughter into a "fussy little monster?" Those thoughts hurt both of you.
Sorry, sweetheart, if I sound bossy here. But you have just admitted to the whole world that you have completely lost all perspective, and it's eating you up. Get help. Get help. Get help.
