Trouble with Breastfeeding

Julie
Anyone else having a hard time pumping or breastfeeding? I feel like it is making me depressed and I don't know what to do. I feel like a failure if I quit but I think it's the only way I will be happy again. I just hate pumping and I've had 2 breast infections in the past 2 weeks. My husband is constantly noticing how upset and depressed I seem over it. He is making me feel a little guilty though if I quit. Anyone else experiencing this? 
Also, if you're formula feeding what formula are you using?
