Terrified of post partum

Although I’m so so excited to become a mom for the first time and see my partner become an amazing father, I keep seeing people posting online how miserable they are post partum and how hard it is having a new born. The posts seem to be like 80% negative and it’s making me so scared to give birth. We’re so ready for this baby, we’re financially stable, have supportive family and employers and a beautiful home, but I just can’t shake the feeling that I’m going to be miserable because that’s all people seem to talk about.

Can anyone reassure me?

Thanks in advance 💖
