Breastfeeding & PPD

I want to breastfeed so bad it hurts. But I have no appetite to keep up the nutrients. I’m constantly lightheaded and dizzy and the hormones from breastfeeding are making me sink into this depression so bad. I just want to quit so bad but I feel SO guilty and selfish for it. I love the skin to skin we do but i feel like it’s sucking the life out of me & I just want to feel somewhat normal again
