Post partum

So let me just start by saying I gave birth to a healthy babygirl on 3/20/21. What went from me being so ready to give birth to I wish she was still inside me safe. The day I came home 3/22/21 I realized how scared I was of my new life and how happy I was to now I can’t stop crying in the blink of an eye. I fear something happening at night while I sleep and what’s worse is I have the hardest time even getting her to sleep in her bassinet as she just screams in there. I have trouble with the car seat, I can’t breastfeed as she doesn’t latch to me. Everything has been so overwhelming. My body still hurts from labor and at this point I feel worn out. How do you love someone so much but feel like giving up?? I have a good support system with my family but they’re all an hr away all I have is my boyfriend here and he’s just as confused as I am with why I feel like this and I hate to make him feel bad for me. I just don’t know where to start with everything
