Pregnant and Terrified

I just found out  that I'm pregnant. Don't get me wrong I'm THRILLED. But I'm also terrified that one 1) I'm going to be a bad mother 2) I'm not going to be able to get everything my baby needs before he/she arrives
I guess it never really hit me how hard it may be until I say those two lines. Then looking over a registry online really hit home and made me so overwhelmed. Am I in over my head? We've planned to have a baby, it's not an accident but I'm feeling so stressed at the moment. Am I crazy or has anyone else felt this way even though they've planned to have a baby? I hope this doesn't last long because I want to enjoy being pregnant! 😭
