Is this anxiety or PPD?

LO is just over a month.... I had a c section and tried to breastfeed but that didn't work out and I had to stop. The day I got home from the hospital I had a massive melt down because I felt useless especially since I couldn't breastfeed. Over the next couple days I got better but still a lot of crying and feeling useless because I couldn't get out of bed to help the hubby and what not. I fought through it and sometimes I still get overwhelmed.... Hubby had to go back to work and he works the 4 to midnight shift. He doesn't get home until 1am. Nights are stressful bc he's tired and I'm tired and LO wakes up and sometimes doesn't go back to bed for at least another 2 hours. Today had a massive meltdown. LO will not sleep on his own and fights his sleep... All day after the hubby left for work I tried to get him to nap and he just wouldn't go down... Lots of crying and cuddling... I hadn't eaten anything since 11am and just could not take it... I just feel like I'm not a good mom and LO is not happy... I just feel alone and I'm afraid to go out with LO alone bc I'm afraid of his meltdowns and then I'm home alone to calm him down. I get aggravated with the hubby easily. I'm home on maternity leave for 3 more months and idk if I have anxiety or if I'm developing PPD. Hubby doesn't understand that I just need someone to talk to when he's at work that I just feel lonely. Anyone else going through something like this?
