Post partum depression?

I am pissed, I'm hurt, I'm mad as all hell. Im emotional over everything. Tomorrow marks the 1 year anniversary of pregnancy loss for me. I did get pregnant after a few months and I ended up having my daughter 5 weeks early. Shes precious and I love her beyond words. Since I've had her everything seems to bring me down. I'm pissed I had her early because I feel like my body has failed me like it did previously and im pissed I didn't get a chance to take maternity photos. I'm pissed because my birth didn't go as planned and breast feeding hasn't worked out. I feel like I'm failing at everything. On top of it, I'm living with my in-laws and its making me so miserable that I actually thought about a womens shelter as an alternative for living arrangements. Could this be post partum. My life feels like a never ending battle of bullshit and drama and I feel like nobody understands.
