Tired of pumping

Jesa
So when my daughter was born I had every intention to breastfeed her. But from the beginning we have had challenge after challenge. First her suck wasn't strong so she was losing weight fast. So I decided to pump and that was going good for awhile until I got mastitis and pretty much lost my supply. I've being desperately trying to get it back but it's just not working and I've been doing this for almost 2 months straight. Everytime I pump I get maybe an ounce from both. If I'm lucky. I've tried the tea and supplements and power pumping. Nothing helps. I'm just tired and ready to give up on pumping. My daughter is fed and happy. My husband will not leave me alone about it though. He is always saying that I'm not trying hard enough and that breast milk is best for her so that's what she should have. I'm just tired and I don't know how to make him leave me alone and understand the struggle I've been going through.
