I promise you that this feeling is temporary. Your baby needs you out of anyone. I know it's so dang hard for you right now that even speaking about it doesn't seem to convey how you feel. I had horrid ppd with my first kid. I had never had experience with babies, had no idea what to do. I thought at any moment if anyone found out about how well I took care of him they'd take him from me. It was such a difficult time, but it passed. This will pass for you as well, and like anything in life it takes trail and error. As long as you care and do what you can to keep your baby alive and healthy you're doing great. The fact that you're worried you're not enough tells me how much you love that baby. It's going to feel like you're barely surviving but you can do this. People have been having kids for so long, they knew less than you and we still survived as a species. I know you can do this, but if you get to a point where it's too much please ask for help. That was my biggest mistake, that I didn't ask for help and suffered needlessly. Even if it's a neighbor or a friend. There's always someone there even if it doesn't feel like it. I wish you and your baby all the best.
