Feeling really depressed after bringing baby home.

Obviously I'm so happy I got to bring my beautiful baby girl home just a week ago but recently my mental health has taken a huge hit. Healing from an emergency C-Section and trying to care for a newborn has me mentally and physically drained. My spouse has done everything in the world to make it easier on me but I'm still feeling a lot of pressure. I miss working and I honestly miss being able to sleep through an entire night. I feel so selfish but I also feel so guilty because it's hard to get up out of bed and change or feed the baby, I notice myself almost nodding off during a feed and my husband and I have been pumping so there's a good food supply in case he's the only one up with the baby and I definitely feel a little jealous because that's one of the few things just for me and the baby, whereas it's easier for him to just scoop her up and lay on the floor to play with her. It has me really torn up and I've been having a couple impromptu crying fits these last few days. My depression hasn't been this bad since the start of my pregnancy and I'm not sure if It's just a change in hormones or if it's something more serious. I just want to get over this hump, but it's starting to feel harder every day and I hate feeling like I'm dragging my family down with me.
